The compartments of these tanks are closed and filled with air. Gage A reads 207 kPa. Gage B registers a vacuum of 254 mm of mercury. What will gage C read if it is connected to compartment 1 but inside compartment 2

Answers

Answer: 240.9 Kpa

Explanation:

Let first changes pressure Gage B from mm of mercury to KPa. That is,

254mm of mercury = 33.86KPa.

To calculate the pressure at C, we need to consider the atmospheric pressure and calculate the absolute pressure of the tank compartment

At gage C, the reading will read P1– P2

Where P1 = absolute pressure

Give that the pressure at B = 254 mm Hg

But (101.33/760) = 33.87 kPa

Where 101.33 = atmospheric pressure

Therefore,

P2 = 101 - 33.87 = 67.13 kPa

P2 = Pa ( pressure at A

Absolute P1 = Patm + Pa= 101 + 207 = 308 kPa abs.

Therefore, Pc = 308 - 67.13

Pc = 240.9Kpa

Therefore, gage C will read 240.9 Kpa if it is connected to compartment 1 but inside compartment 2

The compartments of these tanks are closed and filled with air. Gage A reads 207 kPa. Gage B registers

What signal propagation phenomena causes the diffusion, or the reflection in multiple different directions, of a signal?

Answers

In the radio communication system, multipath is the propagation phenomenon that causes diffusion or reflection in multiple different directions of a signal.

Multipath is a propagation mechanism that impacts the propagation of signals in radio communication. Multipath results in the transmission of data to the receiving antenna by two or more paths. Diffusion and reflection are the causes that create multiple paths for the signal to be delivered.

Diffraction occurs when a signal bends around sharp corners; while reflection occurs when a signal impinges on a smooth object. When a signal is received through more than one path because of the diffraction or reflection, it creates phase shifting and interference of the signal.

Speculators in energy markets have been blamed for recent volatility in gas and oil prices. Consider the following scenario: In response to this criticism of speculators, regulators impose restrictions on them that make it costlier for them to participate in the energy markets. Immediately prior to the effect of the new regulations, in the oil derivatives market, hedgers are net long. At this time, hedgers in the gas derivatives market are net short. Assuming nothing else changes, predict the effect of the new regulations on the trend (drift) in oil futures prices and the trend (drift) in gas futures prices. Briefly describe how these changes in the trends will impact the cost of hedging in the oil and gas markets. Explain your reasoning.

A mass of 5 kg of saturated liquid-vapor mixture of water is contained in a piston-cylinder device at 125 kPa. Initially, 2 kg of the water is in the liquid phase and the rest is in the vapor phase. Heat is now transferred to the water, and the piston, which is resting on a set of stops, starts moving when the pressure inside reaches 300 kPa. Heat transfer continues until the total volume increases by 20 percent.


Determine:

(a) the initial and final temperatures,

(b) the mass of liquid water when the piston first start moving

Answers

a)  The initial and final temprature are 99.61°C and T3 = 259.07°C

b)   The mass of liquid water when the piston first start moving is 0g

Using the data provided:

Initial Pressure = P1 = 125kPa

Mass of Saturated Vapor Liquid = m = 5kg

Initial Mass of Liquid water = mf = 2kg

Initial Mass of Vapor = mg = 3kg

The temperature for a mixture of liquid steam saturated with water according to the thermodynamic table is:

T₁ = 99.61°C

The specific volume is:

vf = 0.001043m³/kg

And the saturated volume is:

vg = 1.6941m³/kg

Therefore, the volume in state 1 will be equal to:

V1 = mfvf + mgvg

V1 = (2kg)(0.001043m³/kg) + (3kg)(1.6941m³/kg)

V1 = 5.084m³

In state 3 then the volume will be equal to:

V3 = 1.2V1

V3 = 1.2(5.084m³)

V3 = 6.1008m³

Then the specific volume will be equal to:

v3 = V₃/m

v3 = 6.1008m³/5kg

v3 = 1.2202m³/kg

For a pressure of 300 kPa and the previous specific volume found through the thermodynamic table, the value of the temperature is:

T3 = 259.07°C

Question b) When the piston first stats moving at P₂ = 300kPa and V₂ = V₁ = 5.084m³

v₂ =V₂/m

v₂ = 5.084m³/5kg

v2 = 1.0168m³/kg

While at 300 kPa the value of the vapor saturated vg = 0.88578m³/kg This implies that the condition is met:

v2 > vg

Therefore, no liquid is there in-cylinder when piston stats moving, mf = 0kg

The effective temperature of a body having an area on 0.12 m² is 527°C what is the total rate of energy emission?

Answers

The total rate of energy emission is 2786.9 W.

Total Rate of Energy Emission

Radiation is a type of heat transfer where the heat energy is conveyed from photons or electromagnetic waves.  The rate of energy emission can be calculated multiplying the Stefan–Boltzmann law (σ\(*T^4\)) by area (A). Therefore, you have:

Total Rate of Energy Emission (E)= σ\(*A*T^4\), where:

σ = Stefan–Boltzmann constant = \(5.67*10^{-8}\) \(\frac{W}{m^2K^4}\)

A= area

T=temperature (K)

For solving this exercise, you should apply this formula. For your question:

σ = Stefan–Boltzmann constant = \(5.67*10^{-8}\) \(\frac{W}{m^2K^4}\)

A= 0.12 m²

T=527+273=800 K

Thus, the Total Rate of Energy Emission (E) will be:

E=σ\(*A*T^4\)

\(E=(5.67*10^{-8}\frac{W}{m^2K^4})*(0.12*m^{2} )*(800K)\\ \\ E=2786.9 W\)

A battery with an f.e.m. of 12 V and negligible internal resistance is connected to a resistor of 545 How much energy is dissipated by the resistor in 65 s?​

Answers

Answer:

When are resistors in series? Resistors are in series whenever the flow of charge, called the current, must flow through devices sequentially. For example, if current flows through a person holding a screwdriver and into the Earth, then  

R

1

 in Figure 1(a) could be the resistance of the screwdriver’s shaft,  

R

2

 the resistance of its handle,  

R

3

 the person’s body resistance, and  

R

 the resistance of her shoes.

Figure 2 shows resistors in series connected to a voltage source. It seems reasonable that the total resistance is the sum of the individual resistances, considering that the current has to pass through each resistor in sequence. (This fact would be an advantage to a person wishing to avoid an electrical shock, who could reduce the current by wearing high-resistance rubber-soled shoes. It could be a disadvantage if one of the resistances were a faulty high-resistance cord to an appliance that would reduce the operating current.)

Two electrical circuits are compared. The first one has three resistors, R sub one, R sub two, and R sub three, connected in series with a voltage source V to form a closed circuit. The first circuit is equivalent to the second circuit, which has a single resistor R sub s connected to a voltage source V. Both circuits carry a current I, which starts from the positive end of the voltage source and moves in a clockwise direction around the circuit.

Figure 2. Three resistors connected in series to a battery (left) and the equivalent single or series resistance (right).

To verify that resistances in series do indeed add, let us consider the loss of electrical power, called a voltage drop, in each resistor in Figure 2.

According to Ohm’s law, the voltage drop,  

V

, across a resistor when a current flows through it is calculated using the equation  

V

=

I

R

, where  

I

 equals the current in amps (A) and  

R

 is the resistance in ohms  

(

Ω

)

. Another way to think of this is that

A liquid stream containing 50. 0 mole% benzene and the balance toluene at 25°C is fed to a continuous single-stage evaporator at a rate of 1320 mol/s. The liquid and vapor streams leaving the evaporator are both at 95. 0°C. The liquid contains 42. 5 mole% benzene and the vapor contains 73. 5 mole% benzene. (a) Calculate the heating requirement for this process in kW. (b) Using Raoult's law (Section 6. 4b) to describe the equilibrium between the vapor and liquid outlet streams, determine whether or not the given benzene analyses are consistent with each other. If they are, calculate the pressure (tor) at which the evaporator must be operating; if they are not, give several possible explanations for the inconsistency

Answers

(a) The heating requirement for this process is 2.95 x 10⁶ kW

(b) The given benzene analyses are not consistent with each other.

(a) To calculate the heating requirement for this process, we need to determine the heat that must be supplied to the evaporator to vaporize the liquid stream and heat the vapor to the outlet temperature of 95.0°C. We can use the following energy balance:

Q = m(L)v + m(V)h

where Q is the heat required, m(L) and m(V) are the mass flow rates of the liquid and vapor streams, respectively, and v and h are the specific volumes and enthalpies of the liquid and vapor streams, respectively.

To convert the given mole fractions to mass fractions, we need to use the molecular weights of benzene and toluene:

MW_benzene = 78.11 g/mol

MW_toluene = 92.14 g/mol

The mass fraction of benzene in the liquid stream is:

y_B = 0.50

M_B = y_B x MW_benzene / ((1 - y_B) x MW_toluene + y_B x MW_benzene) = 0.436

Similarly, the mass fraction of benzene in the liquid outlet stream is:

x_B = 0.425

M_B = x_B (MW_benzene) / ((1 - x_B)  MW_toluene + x_B ( MW_benzene) = 0.378

And the mass fraction of benzene in the vapor stream is:

z_B = 0.735

M_B = z_B x MW_benzene / ((1 - z_B) x MW_toluene + z_B x MW_benzene) = 0.532

Now we can use Raoult's law to relate the vapor pressures of benzene and toluene in the liquid and vapor streams:

P_B = y_B x P°_B

P_T = (1 - y_B) x P°_T

P'_B = z_B x P°_B'

P'_T = (1 - z_B) x P°_T'

where P°_B and P°_T are the vapor pressures of pure benzene and toluene at 25°C, and P°_B' and P°_T' are the vapor pressures of pure benzene and toluene at 95°C. We can look up these values in a reference table:

P°_B = 12.7 kPa

P°_T = 3.8 kPa

P°_B' = 95.4 kPa

P°_T' = 12.6 kPa

Substituting these values and solving for the vapor pressure of benzene in the liquid and vapor streams, we get:

P_B = 6.35 kPa

P'_B = 50.80 kPa

Now we can calculate the mass flow rates of the liquid and vapor streams:

m(L) = 1320 / (1 + V/L)

m(V) = 1320 - m(L)

where V/L is the ratio of the vapor flow rate to the liquid flow rate, which we can calculate from the vapor-liquid equilibrium relation:

V/L = z_B / (y_B - z_B) = 1.53

Substituting these values and the specific volumes and enthalpies of benzene and toluene, which we can look up in a reference table, we get:

v_L = 0.001319 m³/mol

v_V = 0.03147 m³/mol

h_L = -15702 J/mol

h_V = -11006 J/mol

(d) What is the probability that he goes to KARIM or orders Afghani Chicken or both?

Answers

Answer:

a) 0.42

b) Independent

c) 30%

d) 0.88

Explanation:

Person chooses Chicken's item : 70% = 0.7

Person chooses fish's item : 30% = 0.3

Visits in which he orders Afghani Chicken = 60% = 0.6

a) Probability that he goes to KARIM and orders Afghani Chicken:

P = 0.7 * 0.6 = 0.42

b) Two events are said to be independent when occurrence of one event does not affect the probability of the other event's occurrence. Here the person orders Afghani Chicken regardless of where he visits so the events are independent.

c)  P = 0.30 because he orders Afghani Chicken regardless of where he visits.

d)  Let A be the probability that he goes to KARIM:

P(A) = 0.7 * ( 1 - 0.6 ) = 0.28

Let A be the probability that he orders Afghani Chicken:

P(B) =  0.3 * 0.6 = 0.18

Let C be the probability that he goes to KARIM and orders Afghani chicken:

= 0.7 * 0.6 = 0.42

So probability that he goes to KARIM or orders Afghani Chicken or both:

P(A) + P(B) + P(C) = 0.28 + 0.18 + 0.42 = 0.88

This demographic includes all individuals who are legally eligible to cast their ballot in any given election. To determine the adult population, it's important to note that not all adults are in the labor force. Some individuals may be out of work and not actively seeking employment, which means they are not included in the labor force.

Similarly, those who are not working due to disability or other reasons are also not included in the labor force. The adult population can be calculated by adding the labor force and not the labor force together. The labor force is the number of individuals who are employed or actively seeking employment. Those who are not in the labor force include retirees, stay-at-home parents, and individuals who are unable to work due to disability or other reasons.

So, adding the labor force and not in the labor force together can give us the total adult population of a particular region or country.

3.You must use else after every if statement.
what is answer?

Answers

It's important to note that this speed difference is only noticeable for large programs. For small programs, the difference is negligible.

1. Shortcut operators are faster than the conventional arithmetic operators: This statement is true. Shortcut operators are faster because they combine arithmetic operations with variable assignments in a single statement. For example, instead of writing "a = a + 2", you can write "a += 2". This saves time and reduces the amount of code you need to write. However, it's important to note that this speed difference is only noticeable for large programs or when dealing with complex calculations. For small programs, the difference is negligible.
2. You can declare more than one variable in a single line: This statement is also true. In many programming languages, you can declare and initialize multiple variables on the same line. For example, instead of writing "int a; int b; int c;", you can write "int a, b, c;". This saves space and makes your code more concise. However, it's important to note that you should only do this if the variables are related and have the same data type.
3. You must use else after every if statement: This statement is false. It's not necessary to use else after every if statement. You can use if statements on their own if you don't need to execute any code if the condition is not true. However, if you need to execute code in both cases (true and false), then you should use else. It's also important to note that you can use else if to test for additional conditions if the first if statement is not true.

Using Huffman encoding scheme on a set S of n symbols with frequencies fi, f2, ..., fn, what is the longest a codeword could possibly be? Give an example set of frequencies that would produce this case. Note that your set of frequencies must be defined in such a way that it is generalizable for any value of n. This set of frequencies must be valid, meaning that the frequencies of all characters sums to 1, though you do not need to prove this. Additionally, you do not need to prove that your proposed set of frequencies will produce the desired result.

Answers

Huffman encoding's longest codeword is n-1 bits long. For instance, f i = 2(i-1)/2n.

What is the longest codeword that may be used in a Huffman encoding of an n-symbol alphabet?

The length of the longest codeword is n 1. This number is obtained by encoding n symbols, where n 2 of them have probabilities of 1/2,1/4,...,1/2n-2, and two of them have probabilities of 1/2n-1. Never can a codeword be longer than length n 1.

For an input alphabet of size n, what is the tallest Huffman tree that can be constructed?

The longest code, or the maximum depth, is 255.ac if by "all bytes" you mean the 256 potential byte values that can be used as symbols.

(a) Design a high-pass filter with a cutoff frequency of 40 kHz. Use0.01 uF capacitor and an appropriate resistor. B) Sketch and label the circuit. C) What is the gain of the filter at the cutoff frequency? Give your answer both as ratio (Vout/Vin) and in dB. D) What is the gain of the filter at a frequency of 55 kHz? Give your answer both as a ratio (Vout/Vin) and in dB.

Answers

Answer:

a) 397.89 ohm

b) attached below

c) 0.707  as a ratio

Gain in dB = 20 log 0.707 = -3 dB

d)  0.8087

Gain in dB = 20 log \(|\frac{Vout}{Vin}|\) = -1.844 dB

Explanation:

A) Find the appropriate resistor

c = 0.01 uf

fc = 40 kHz

cut-off frequency ; fo = \(\frac{1}{2\pi RC }\)

from the above equation  R = \(\frac{1}{2\pi foC}\)  = 397.89 ohm

B) sketch of the circuit  is attached

C) The gain of the filter at the cutoff frequency

fc = 40 kHz,  

C = 0.01 uF ⇒ \(\frac{-j}{2\pi foC }\) =  -j 397.89

Vout = Vin * ( R / R- C )

Vout = Vin * ( 397.89 / (397.89 - j 397.89))

Vout = \(\frac{1}{\sqrt{2} }\)  Vin ∠45⁰

therefore gain = |\(\frac{Vout}{Vin }\)| = \(\frac{1}{\sqrt{2} }\) = 0.707  as a ratio

Gain in dB = 20 log 0.707 = -3 dB

D) Gain of filter at 55 kHz

c = 0.01 uF =  \(\frac{-J}{2\pi foC }\) =  -j 289.373 ohms

Vout = Vin * \(\frac{R}{R-C}\)  

        = Vin * ( 397.89 / ( 397.89 - j 289.373))

Gain in ratio \(|\frac{Vout}{Vin}|\) = 0.8087 ∠ 36.03⁰

therefore gain in ratio = 0.8087

Gain in dB = 20 log \(|\frac{Vout}{Vin}|\) = -1.844 dB

A 1-ft rod with a diameter of 0.5 in. is subjected to a tensile force of 1,300 lb and has an elongation of 0.009 in. The modulus of elasticity of the material is most nearly:

Answers

Answer:

E = 8.83 kips

Explanation:

First, we determine the stress on the rod:

\(\sigma = \frac{F}{A}\\\\\)

where,

σ = stress = ?

F = Force Applied = 1300 lb

A = Cross-sectional Area of rod = 0.5\(\pi \frac{d^2}{4} = \pi \frac{(0.5\ in)^2}{4} = 0.1963\ in^2\)

Therefore,

\(\sigma = \frac{1300\ lb}{0.1963\ in^2} \\\\\sigma = 6.62\ kips\)

Now, we determine the strain:

\(strain = \epsilon = \frac{elongation}{original\ length} \\\\\epsilon = \frac{0.009\ in}{12\ in}\\\\\epsilon = 7.5\ x\ 10^{-4}\)

Now, the modulus of elasticity (E) is given as:

\(E = \frac{\sigma}{\epsilon}\\\\E = \frac{6.62\ kips}{7.5\ x\ 10^{-4}}\)

E = 8.83 kips

A musical tone sounded on a piano has a frequency of 410 Hz and a wavelength of 0.80 m. What is the speed of the sound wave

Answers

The speed of a sound wave can be calculated using the formula:Speed (v) = Frequency (f) × Wavelength (λ)Given that the frequency of the musical tone is 410 Hz (cycles per second) and

The speed of the sound wave is 328 m/s. This is calculated by multiplying the frequency (410 Hz) by the wavelength (0.80 m) using the formula for wave speed. The frequency represents the number of cycles per second, and the wavelength is the distance between two corresponding points on the wave. Multiplying these values gives the distance traveled by the wave per second. In this case, the sound wave travels at a speed of 328 meters per second. The speed of sound in air is approximately 343 m/s, so the given value of 328 m/s falls within the expected range.

a. What will happen when you pass a constant DC current through an inductor?
b. what will happen when you pass an AC current through an inductor?
c. If a current existed near the inductor, how would the inductor respond?
d. Describe one experiment you could perform to test your answers to these questions.

Answers

a. When you pass a constant DC current through an inductor, the inductor will resist the change in current and create a magnetic field. This magnetic field will increase over time, causing the inductor to store energy in the form of magnetic potential energy.

b. When you pass an AC current through an inductor, the inductor will still resist the change in current and create a magnetic field. However, the direction of the current in the AC signal will alternate, causing the magnetic field to constantly increase and decrease. This will result in the inductor storing energy during one half of the AC cycle and releasing it during the other half.

c. If a current existed near the inductor, the inductor would respond by inducing a voltage in the nearby circuit. This is because the magnetic field produced by the inductor will interact with the current in the nearby circuit, causing a change in voltage.

d. One experiment you could perform to test these answers would be to set up a simple circuit with an inductor and a resistor. Then, you could pass a constant DC current through the circuit and measure the voltage across the inductor. Next, you could pass an AC current through the circuit and measure the voltage across the inductor again. Finally, you could introduce a nearby current and observe the effect on the voltage across the inductor. By comparing the results of these tests, you could confirm the behavior of the inductor in different situations.

Propane gas (C3H8) at 25C, 1 atm enters an insulated reactor operating at steady state and burns completely with air entering at 25C, 1atm. Plot the adiabatic flame temperature versus percent of theoretical air ranging from 100 to 400%. Why does the adiabatic flame temperature vary with increasing combustion air?




Note: Just pick one or two AFR's, 2125 K for 120% Theoretical Air

Answers

As the percent of theoretical air increases, the adiabatic flame temperature also increases. This is because more air means more oxygen is available for the combustion reaction, which allows the reaction to proceed more efficiently and release more heat. This increase in heat causes the temperature of the gas to rise.

An adiabatic flame temperature is the temperature reached by a gas as it undergoes a chemical reaction, such as combustion, in an insulated environment where no heat is lost to the surroundings. In this case, the adiabatic flame temperature of propane gas burning with air can be plotted versus the percent of theoretical air, which is the amount of air required for complete combustion of the fuel.

At a percent of theoretical air of 120%, the adiabatic flame temperature is 2125 K. This temperature will continue to rise as the percent of theoretical air is increased further.
