6.15 A modified CRC procedure is commonly used in communications standards. It is defined as follows: X¹6D (X) + XL (X) R(X) = Q+ P(X) P(X) FCS = L(X) + R (X) where L(X) = X15 + X14 + X¹3 + + X + 1 and k is the number of bits being checked (address, control, and information fields). a. Describe in words the effect of this procedure. b. Explain the potential benefits. c. Show a shift-register implementation for P(X) X16+ X12 + X³ + 1.

Using the normalized distribution it is possible to calculate the value of Z score and for cases where there is a 99% chance, so Zscore is -3.6 and X= 16.45.

This curve determines the probability of the event associated with it occurring. The Gaussian distribution is the most common, hence it is known as the Normal Distribution. The area under the distribution curve is always equal to 1.0.

The formula for this distribution can be described as:

\(Z score = \frac{x-\mu}{\sigma}\)

Where:

In this case,

\(Z score =\frac{1-10}{2.5} \\Z score = -3.6\)

P-value from Z-Table will be P(x<1) = 0.00015911

For 99% we have that z will be 2.58, so

\(2.58=\frac{x-10}{2.5}\\x = 16.45\)

A(n) message is a set of symbols that the sender transmits. A message can be verbal or nonverbal, and it can be transmitted through various communication channels, such as face-to-face interaction, email, text message, or phone call.

The symbols in a message can include words, tone of voice, body language, facial expressions, images, and other visual aids. The sender encodes the message in a way that is intended to convey a specific meaning to the receiver. However, the receiver may decode the message differently based on their own experiences, attitudes, and biases.

Therefore, effective communication requires not only clear encoding but also accurate decoding and feedback. Miscommunication can occur when the sender and receiver have different assumptions or expectations about the meaning of the symbols used in the message. Effective communication involves being aware of these potential barriers and using strategies to overcome them.

Answer:

The temperature of the outer wall surface will be closer to the temperature of the surrounding air.

Explanation

Since the outer wall has a convective heat transfer coefficient that is 3 time the one in the inner surface due to the wind, the outer wall will have a temperature closer to the surrounding air's temperature because the heat that flows from the warmer inner room wall will be rapidly conducted away from the surface of the outer wall by the prevailing wind, leaving it with a reduced temperature that will be closer to the temperature of the surrounding air.

The power required to drive the 42" x 70" Nordberg Gyratory Crusher is approximately 189.97 kW.

To calculate the power required to drive a 42" x 70" Nordberg Gyratory Crusher, we will use the following equation:

Power (P) = Work done per unit time (W) / Time (t)

Given the design throughput of 1,200 tph (tons per hour) and considering the maximum feed size of 1,000 mm and a product where 80% is smaller than 150 mm with a 25 mm throw, we can use the following steps:

1. Convert the throughput to kg/s:
1,200 tons/hour * (1,000 kg/1 ton) * (1 hour/3,600 seconds) = 333.33 kg/s

2. Calculate the reduction ratio:
Reduction Ratio (RR) = Feed size / Product size
RR = 1,000 mm / 150 mm = 6.67

3. Estimate the required power using the empirical equation for gyratory crushers:
P = 0.075 * W * (1 + sqrt(1 + 4 * (RR - 1))) / t
P = 0.075 * 333.33 kg/s * (1 + sqrt(1 + 4 * (6.67 - 1))) / (1/333.33 s)
P ≈ 189.97 kW

Thus, the power required to drive the 42" x 70" Nordberg Gyratory Crusher is approximately 189.97 kW.

The Ackermann function is a useful tool in computer science for studying the limits of computation. However, its exponential growth rate means that it quickly becomes impractical to evaluate for large values of m and n.

The Ackermann function is a recursive function that is defined for non-negative integers m and n. The function ack(m, n) evaluates the Ackermann function for the given values of m and n. The base case of the function is when m=0, in which case the function returns n+1. If m>0 and n=0, the function calls itself with (m-1,1) as arguments. If m>0 and n>0, the function calls itself recursively with arguments (m-1, ack(m,n-1)).

For ack(3,4), the function evaluates to 125. For larger values of m and n, the Ackermann function grows very quickly, making it difficult to evaluate the function for large values. In fact, the function grows so quickly that it quickly exceeds the limits of most computer programs and hardware.

To determine the average number of workers at the trailer, we can use the M/M/1 queuing model, where arrivals follow a Poisson process and service times follow an exponential distribution.So, the correct answer is:2 workers

Given that workers arrive at an average rate of 8 per hour, the arrival rate (λ) is 8 per hour. The average service time (1/μ) is 6 minutes, which can be converted to hours by dividing by 60, resulting in μ = 1/10 per hour.

Using the M/M/1 queuing formula for the average number of workers (N) in the system:

N = λ / (μ - λ)

Substituting the values, we have:

N = 8 / (1/10 - 8) = 8 / (1/10 - 80) = 8 / (-79/10) = -80/79 ≈ -1.01

Since the number of workers cannot be negative, we take the absolute value, resulting in approximately 1.01 workers.

However, since the question asks for the average number of workers at the trailer, including the one whose permit is being worked on, we need to consider at least one worker. Therefore, we round up the result to the nearest whole number, which gives us an average of 2 workers at the trailer.

The breaking strength X kg of a certain type of plastic block is normally distributed with a mean of 1500 kg and a standard deviation of 50 kg.

(a) As per the given statement, it is a right-tailed test. Let Z be the standard normal variable, then Z = (X - μ)/σ

Where, μ = 1500 kg, σ = 50 kg

For no more than 5% of the blocks to break, the corresponding Z-score is given as Z = 1.645. By using the formula, we have:

1.645 = (X - 1500)/50X = (1.645 × 50) + 1500X = 1822.25 kg

(b)Here, X = 1400 kg, μ = 1500 kg, and σ = 50 kg.

Let Z be the standard normal variable, then Z = (X - μ)/σZ = (1400 - 1500)/50 = -2P(Z < -2) = 0.0228.

The minimum power [W] of the lathe should be approximately 842.4 W to turn the stainless steel cylindrical part under the given cutting conditions.

To calculate the minimum power [W] required for the lathe to turn the stainless steel cylindrical part, we need to determine the cutting speed, the material removal rate, and the specific cutting energy, and use these values in the following equation:
P = MRR × U × K
where:
P = power [W]
MRR = material removal rate [mm^3/s]
U = specific cutting energy [J/mm^3]
K = a constant factor based on units (e.g., K = 60 for metric units)
First, let's calculate the cutting speed:
V = π × D × N / 1000
where:
V = cutting speed [m/s]
D = diameter [mm]
N = spindle speed [rpm]
Plugging in the values, we get:
V = π × 75 × 450 / 1000 = 99.82 [m/min]
Next, we can calculate the material removal rate:
MRR = depth of cut × feed × width of cut × V
where:
width of cut = π × D / 2 = 117.81 [mm]
Plugging in the values, we get:
MRR = 2 × 0.5 × 117.81 × 99.82 / 1000 = 11.70 [mm^3/s]
Next, we need to determine the specific cutting energy. For stainless steel, a typical value for the specific cutting energy is around 1.2 J/mm^3.
Finally, we can calculate the minimum power required for the lathe:
P = MRR × U × K = 11.70 × 1.2 × 60 = 842.4 [W]
Therefore, the minimum power [W] of the lathe should be approximately 842.4 W to turn the stainless steel cylindrical part under the given cutting conditions.

Question:

In the given circuit, V(t)=12cos(2000t+45)V, R1=R2=2Ω, L1=L2=L3=3mH and C1=250μF. You are required to find the Thevenin equivalent of this circuit using phasors.

a. If you write the Thevenin voltage, Vth, in phasor form, what is the magnitude of this phasor? Put your answer in the box below without units.

b. What is the value of the angle associated with the phasor Vth, in degrees?

c. Now, calculate the Thevenin impedance, Zth. What is the magnitude of this phasor?

d. What is the angle associated with the phasor Zth, in degrees?

Answer:

Vth = 6 < 45° V

Zth = 1.414 < 45°

a. The magnitude of the Thevenin voltage is 6 V

b. The phase angle of the Thevenin voltage is 45°

c. The magnitude of the Thevenin impedance is 1.414 V

d. The phase angle of the Thevenin impedance is 45°

Explanation:

The given voltage is

V(t)=12cos(2000t+45)

In phasor form,

V(t) = 12 < 45° V

So the magnitude of voltage is 12 V and the phase angle is 45°

Also the frequency ω = 2000

then the inductance is

L₁ = L₂ = L₃ = jωL = j×2000×0.003 = j6 Ω

and the capacitance is

C₁ = 1/jωC = 1/(j×2000×250x10⁻⁶) = -j2 Ω

and the resistance is

R₁ = R₂ = 2 Ω

Thevenin voltage:

The Thevenin voltage is the voltage that appears across the open-circuited terminals a-b (after removing L₃)

The Thevenin voltage is given by

Vth = V(t) × [ (R₂ + L₂) / (R₁ + L₁) + (R₂ + L₂) ]

Please note that there is no current flow in the capacitor due to open-circuited terminal a-b

Vth = 12 < 45°  × [ (2 + j6) / (2 + j6) + (2 + j6) ]

Vth = 12 < 45°  × [ (2 + j6) / (4 + j12) ]

Vth = 4.24264 + j4.24264 V

In phasor form,

Vth = 6 < 45° V

a. The magnitude of the Thevenin voltage is 6 V

b. The phase angle of the Thevenin voltage is 45°

Thevenin Impedance:

The Thevenin Impedance is the impedance of the circuit calculated when looking from the terminal a-b

Zth = [ (R₁ + L₁) × (R₂ + L₂) / (R₁ + L₁) + (R₂ + L₂) ] + (-j2)

Zth = [ (2 + j6) × (2 + j6) / (2 + j6) + (2 + j6) ] - j2

Zth = [ (2 + j6) × (2 + j6) / (2 + j6) + (2 + j6) ] - j2

Zth = [ (-32 + j24) / (4 + j12) ] -j2

Zth = [ (1 +j3) ] - j2

Zth = 1 + j Ω

In phasor form,

Zth = 1.414 < 45°

c. The magnitude of the Thevenin impedance is 1.414 V

d. The phase angle of the Thevenin impedance is 45°

The first law of thermodynamics states that the total energy of a closed system is constant; energy can neither be created nor destroyed, only transformed from one form to another.

This law can be expressed mathematically as:

dU = dQ - dW

Where dU is the change in internal energy, dQ is the heat added to the system, and dW is the work done by the system.

The second law of thermodynamics states that the entropy of a closed system always increases over time, approaching a maximum value at equilibrium. This law can be expressed mathematically as:

dS > 0

Where dS is the change in entropy.

Using these laws, we can write out the combined statements for the energy functions as follows:

For U = U(S, P):

dU = TdS - PdV

For H = H(S, P):

dH = TdS + VdP

For F = F(T, V):

dF = -SdT - PdV

For G = G(T, P):

dG = -SdT + VdP

a) To make up a 32G × 64 memory, each word being 64 bits in size, we need a total of 32G words. Since each RAM chip has a capacity of 1G × 16, we can calculate the number of RAM chips necessary: = 32 chips

Number of RAM chips = (32G words) / (1G words/chip)

                   = 32 chips

b) Assuming four chips per bank, the number of banks required can be calculated by dividing the total number of chips by the number of chips per bank:

Number of banks = (Number of RAM chips) / (Chips per bank)

              = 32 chips / 4 chips/bank

              = 8 banks

c) Each chip has a word width of 16 bits (1G × 16). To address each chip, we need a total of 16 lines.

d) For a memory that is word addressable, the number of bits needed for a memory address is calculated as follows:

Number of bits = log2(32G words)

              = log2(2^35)   (since 32G = 2^35)

              = 35 bits

e) For chip select, we need enough bits to uniquely identify each chip. Since we have 32 chips, we need 5 bits (2^5 = 32) for chip select. The remaining 30 bits will be used for the address on the chip.

b) \(H_{loss} = 5.02 W\)

c) \(T_s = 302 K\)

d) \(\dot{Q} = 25.125 W\)

Explanation:

Non horizontal pipe diameter, d = 25 cm = 0.25 m

Radius, r = 0.25/2 = 0.125 m

Entry temperature, T₁ = 304 + 273 = 577 K

Exit temperature, T₂ = 284 + 273 = 557 K

Ambient temperature, \(T_a = 25^0 C = 298 K\)

Pipe length, L = 10 m

Area, A = 2πrL

A = 2π * 0.125 * 10

A = 7.855 m²

Mass flow rate,

\(\dot{ m} = 4.5 tons/hr\\\dot{m} = \frac{4.5*1000}{3600} = 1.25 kg/sec\)

Rate of heat transfer,

\(\dot{Q} = \dot{m} c_p ( T_1 - T_2)\\\dot{Q} = 1.25 * 1.005 * (577 - 557)\\\dot{Q} = 25.125 W\)

a) To calculate the convection coefficient relationship for heat transfer by convection:

\(\dot{Q} = h_c A (T_1 - T_2)\\25.125 = h_c * 7.855 * (577 - 557)\\h_c = 0.1599 W/m^2 - K\)

Note that we cannot calculate the heat loss by the pipe to the environment without first calculating the surface temperature of the pipe.

c) The surface temperature of the pipe:

Smear coefficient of the pipe, \(k_c = 0.8\)

\(\dot{Q} = k_c A (T_s - T_a)\\25.125 = 0.8 * 7.855 * (T_s - 298)\\T_s = 302 K\)

b) Heat loss from the pipe to the environment:

\(H_{loss} = h_c A(T_s - T_a)\\H_{loss} = 0.1599 * 7.855( 302 - 298)\\H_{loss} = 5.02 W\)

d) The required fan control power is 25.125 W as calculated earlier above
