Answer:

1700 W

Explanation:

The heat transfer rate P = kA(T - T')/d where k = thermal conductivity of wall = 1.7 W/m-K, A = area of wall = 0.5 m × 1.2 m = 0.6 m², T = temperature of inner surface = 1400 K, T = temperature of outer surface = 1150 K and d = thickness of wall = 0.15 m

So, P = kA(T - T')/d

substituting the values of the variables into the equation, we have

P = 1.7 W/m-K × 0.6 m²(1400 K - 1150 K)/0.15 m

P = 1.7 W/m-K × 0.6 m² × 250 K/0.15 m

P = 255 Wm/0.15 m

P = 1700 W

So, the heat transfer rate through the wall is 1700 W

Answer:

The total load carried by the fiber will be "98%".

Explanation:

The given values are:

\(V_{f}=0.61\)

\(V_{m}=1-V_{f}\)

     \(=1-0.61\)

     \(=0.39\)

\(E_{f}=10 \ Mpa\)

\(\sigma_{f}=0.35 \ Mpa\)

\(E_{m}=0.45 \ Mpa\) , \(\sigma_{m}=9\times 10^{-3} \ Mpa\)

As we know,

⇒  \(E_{e}=fE_{f}+mE_{m}\)

On putting the estimated values, we get

⇒       \(=0.61\times 10+0.39\times 0.95\)

⇒       \(=6.27 \ Mpa\)

Now,

⇒  \(\sigma_{c}=f\sigma_{f}+m\sigma_{m}\)

On putting the estimated values, we get

⇒       \(=0.61\times 0.35+0.39\times 0.009\)

⇒       \(=0.217 \ Mpa\)

Therefore,

The load carried by fiber,

\(=\frac{f\sigma_{f}}{\sigma_{c}}\)

\(=\frac{0.35\times 0.61}{0.217}\)

\(=0.98\) i.e., 98%

Answer:

general duty clause

Explanation:

Answer:

\(\triangle h=4.935m\)

Explanation:

From the question we are told that:

Liquid density \(\rho=800\)

Diameter of pipe \(d=4cm \approx 0.004m\)

Diameter of venture \(d=10cm \approx 0.010m\)

Specific weight of mercury P_mg \(133 kN/m^3\)

Flow rate \(r=0.05 m^3/s\)

Area A:

            \(A_1=\frac{\pi}{4}0.1^2\\A_1=0.00785m^2\\A_2=\frac{\pi}{4}0.04^2\\A_2=0.001256m^2\\\)

Generally the Bernoulli's equation is mathematically given by

\(\frac{P_1}{\rho_1g}+\frac{V_1^2}{2g}=\frac{P_2}{\rho g}+\frac{V_2^2}{2g}\\\)

Where

\(V_1=\frac{r}{A_1} \\\\ &V_1=\frac{r}{A_2}\)

Therefore

\(P_1-P_2=\frac{Pr^2}{2}(\frac{A_1^2-A_2^2}{A_1^2A_2^2})\)

Generally the equation for pressure difference b/w manometer fluid is given as

\(P_1-P_2=(p_mg-pg)\triangle h\)

Therefore

\((p_mg-pg)\triangle h=\frac{Pr^2}{2}(\frac{A_1^2-A_2^2}{A_1^2A_2^2})\)

\(\triangle h=\frac{\frac{Pr^2}{2}(\frac{A_1^2-A_2^2}{A_1^2A_2^2})}{(p_mg-pg)}\)

\(\triangle h=\frac{\frac{(800)(0.05)^2}{2}(\frac{(0.1)^2-(0.4)^2}{(0.1)^2(0.04)^2})}{(1.33*10^3-800*9.81)}\)

\(\triangle h=4.935m\)

Therefore elevation change is mathematically given by

\(\triangle h=4.935m\)

To determine the mass flow rate and inlet area of the steady-flow compressor, we can use the conservation of mass equation and Bernoulli's equation. First, let's calculate the mass flow rate, Substitute the known values into the conservation of mass equation to solve for the mass flow rate (m_dot).

Next, let's determine the inlet area (A1), Apply Bernoulli's equation between the inlet and outlet conditions:
\(P1 + 0.5 * rho1 * V1^2 = P2 + 0.5 * rho2 * V2^2\)
  where:
  - P1 is the inlet pressure
  - rho1 is the density of helium at the inlet conditions
  - V1 is the inlet velocity
  - P2 is the outlet pressure
  - rho2 is the density of helium at the outlet conditions
  - V2 is the outlet velocity

2. Rearrange the equation and solve for the inlet area (A1):
 \(A1 = (m_dot * sqrt(R1 * T1)) / (P1 * V1)\)
  where:
  - m_dot is the mass flow rate
  - R1 is the specific gas constant for helium
  - T1 is the inlet temperature
  - P1 is the inlet pressure
  - V1 is the inlet velocity

Substituting the calculated values,  Mass flow rate (m_dot) = 0.0704 lbm/s
- Inlet area\((A1) = 0.133 ft²\), Therefore, the mass flow rate is 0.0704 lbm/s and the inlet area is 0.133 ft².

To prove or disprove that there are three consecutive odd positive integers that are primes, that is, odd primes of the form p. P+2, and p + 4, we will use the knowledge of primes.Let p be any odd prime number. Then the next two odd numbers after p will be p + 2 and p + 4. We need to prove that among these three numbers, at least one of them will not be a prime number.

Let us take some examples: Let p be 3. Then p + 2 is 5 and p + 4 is 7. All of these numbers are prime, and we have found an example of three consecutive odd positive integers that are primes. Therefore, the statement is true for p = 3.Now let p be 5. Then p + 2 is 7 and p + 4 is 9. Here, 9 is not a prime number, and therefore we have found an example of three consecutive odd positive integers that are not primes.

Thus the statement is false for p = 5. If we continue this pattern, we can see that for every prime number p such that p > 3, p + 4 will be even, and therefore not a prime number. Therefore, we can only find three consecutive odd positive integers that are primes when p = 3. Hence, the statement is true only for p = 3.Thus, we have proved that there are no three consecutive odd positive integers that are prime except for the case where the smallest of the three is 3, that is, p = 3. This can be seen from the fact that every third odd integer is divisible by 3, which means that if the smallest of three consecutive odd integers is not 3, at least one of them will be divisible by 3 and therefore not prime.

Answer: the temperature of the inner surface is 599.55 K

Explanation:

first, let Am²  represent area of the oven surface

now heat transfer rate due to convection

qconv = hAΔT

where ΔT is temperature difference in kelvin (To -Ts) temperature of outer surface - temperature of surroundings

ΔT = 400K - 300k = 100k

and h = 20 W/m².K

so we substitute

qconv = 20 × A × 100 = 2000A W

Now heat transfer due to emission

qemi = ∈α(To⁴ - Ts⁴)A

∈ is emissivity =  0.8, α is boltzman constant = 5.67×10⁻⁸ W/m⁻²K⁻⁴

so we substitute

qemi = 0.8 × 5.67×10⁻⁸ (400⁴ - 300⁴)A

qemi = 4.536×10⁻⁸ × 1.75×10¹⁰ × A

qemi =  793.8A W

NOW total heat loss rate = Qconv + Qemi

2000A + 793.8A = 2793.8A W

so since outer surface is to be maintained at a temp of 400K then heat must be transferred from inner surface to outer surface at the same rate.

Therefore

Heat transfer rate to outer surface by conduction = kA(Ti-To)/L

k is thermal conductivity  0.7 W/m.K, Ti is temperature of inner surface, L is the thickness of plate  0.05m

so Heat transfer rate = 0.7× A × ( Ti - 400 ) / 0.05

Now

This heat transfer rate equals heat loss rate

so  0.7× A × ( Ti - 400 ) / 0.05  =  2793.8 × A

divide both side by A

THEREFORE

Ti = 400 + 199.55

Ti = 599.55 K

∴  the temperature of the inner surface is 599.55 K

Explanation:

m = Mass of automobile = 1100 kg

v = Velocity of car = 120 km/h = \(\dfrac{120}{3.6}\ \text{m/s}\)

h = Height of hill = 80 m

g = Acceleration due to gravity = \(9.81\ \text{m/s}^2\)

Change in kinetic energy

\(KE=\dfrac{1}{2}m(u^2-v^2)\\\Rightarrow KE=\dfrac{1}{2}\times 1100\times (0-(\dfrac{120}{3.6})^2)\\\Rightarrow KE=-611111.11\ \text{J}\)

Change in kinetic energy is \(-6111.11\ \text{kJ}\)

Change in potential energy is given by

\(PE=mgh\\\Rightarrow PE=1100\times 9.81\times 80\\\Rightarrow PE=863280\ \text{J}\)

The change in potential energy is \(863.28\ \text{kJ}\).

In order to determine the height of the tower, we would apply the second equation of motion and assume that the downward motion is negative.

Mathematically, the second equation of motion is given by this formula:

A caisson is a watertight enclosure that can be pumped dry so that construction activities, such as the construction of piers can take place. A caisson is a watertight structure or chamber, usually made of wood, metal, or concrete, that is sunk to the bed of a river, lake, or ocean to provide a foundation or support for a bridge, building, or other structure.

A caisson is constructed onshore and then floated to the location where it is to be sunk into the water. Once in place, water is pumped out of the caisson, and construction workers enter the dry chamber to begin work on the foundation or support structure. The use of caissons has been an important development in the construction of bridges and other structures in areas with deep water or unstable soils.

A foundation called a caisson is used in construction on soft or deep water. It involves filling a series of large, watertight cylinders with concrete and sinking them into the ground.

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

4

 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

So the voltage drop across

When a device wants to transmit data, it sends an RTS frame to the receiving device, requesting permission to transmit. The receiving device then responds with a CTS frame, indicating that it is ready to receive the data. This process ensures that only one device transmits at a time, preventing collisions and improving the overall efficiency of the wireless network.

While the RTS/CTS protocol does involve handshakes between devices, it is primarily designed to prevent collisions rather than improve handshaking. It also does not directly address negative acknowledgements or CRC errors. Instead, it focuses on avoiding collisions, which can be a significant issue in wireless networks with multiple devices competing for the same channel. By implementing the RTS/CTS protocol, wireless networks can reduce collisions, improve data transmission rates, and minimize the potential for data loss or corruption.
