Answer:

a) \(\mathbf{Q_c = -3730.8684 \ Btu/hr}\)

b) \(\mathbf{\sigma _c = 4.3067 \ Btu/hr ^0R}\)

Explanation:

From the properties of Super-heated Refrigerant 134a Vapor at \(T_1 = 40^0 F\), \(P_1 = 30 \ lbf/in^2\) ; we obtain the following properties for specific enthalpy and specific entropy.

So; specific enthalpy \(h_1 = 109.12 \ Btu/lb\)

specific entropy \(s_1 = 0.2315 \ Btu/lb.^0R\)

Also; from the properties of saturated Refrigerant 134 a vapor (liquid - vapor). pressure table at \(P_2 = 160 \ lbf/in^2\) ; we obtain the following properties:

\(h_2 = 115.91 \ Btu/lb\\\\ s_2 = 0.2157 \ Btu/lb.^0R\)

Given that the power input to the compressor is 2 hp;

Then converting to  Btu/hr ;we known that since 1 hp = 2544.4342 Btu/hr

2 hp = 2 × 2544.4342 Btu/hr

2 hp = 5088.8684 Btu/hr

The steady state energy for a compressor can be expressed by the formula:

\(0 = Q_c -W_c+m((h_1-h_e) + \dfrac{v_i^2-v_e^2}{2}+g(\bar \omega_i - \bar \omega_e)\)

By neglecting kinetic and potential energy effects; we have:

\(0 = Q_c -W_c+m(h_1-h_2) \\ \\ Q_c = -W_c+m(h_2-h_1)\)

\(Q_c = -5088.8684 \ Btu/hr +200 \ lb/hr( 115.91 -109.12) Btu/lb \\ \\\)

\(\mathbf{Q_c = -3730.8684 \ Btu/hr}\)

b)  To determine the entropy generation; we employ the formula:

\(\dfrac{dS}{dt} =\dfrac{Qc}{T}+ m( s_1 -s_2) + \sigma _c\)

In a steady state condition \(\dfrac{dS}{dt} =0\)

Hence;

\(0=\dfrac{Qc}{T}+ m( s_1 -s_2) + \sigma _c\)

\(\sigma _c = m( s_1 -s_2) - \dfrac{Qc}{T}\)

\(\sigma _c = [200 \ lb/hr (0.2157 -0.2315) \ Btu/lb .^0R - \dfrac{(-3730.8684 \ Btu/hr)}{(40^0 + 459.67^0)^0R}]\)

\(\sigma _c = [(-3.16 ) \ Btu/hr .^0R + (7.4667 ) Btu/hr ^0R}]\)

\(\mathbf{\sigma _c = 4.3067 \ Btu/hr ^0R}\)

Answer:

\(T_o=82.1sec\)

Explanation:

From the question we are told that:

Lost Time \(t=12secs\)

Sum of critical flow ratios \(X=0.72\)

Generally the Webster Method's equation for Optimum cycle time is is mathematically given by

 \(T_o=\frac{1.5t+5}{1-x}\)

 \(T_o=\frac{1.5*12+5}{1-0.72}\)

 \(T_o=82.1sec\)

To calculate the surface deflection under the center of a tire, we can use the two-layer theory which considers the pavement layer and the subgrade layer. The formula for the surface deflection is given by:

δ = (P/a) * (1-v) * (h1/((E1/((1-v1^2) + (E2/((1-v2^2))))))

Where,

P = tire pressure = 552 kPa

a = contact area of the tire = 152 mm

v = Poisson's ratio

h1 = thickness of the pavement layer = 305 mm

E1 = modulus of elasticity of the pavement layer = 345 MPa

v1 = Poisson's ratio of the pavement layer

E2 = modulus of elasticity of the subgrade layer = 69 MPa

v2 = Poisson's ratio of the subgrade layer

Substituting the given values in the above formula, we get:

δ = (552/152) * (1-0.25) * (305/((345/((1-0.25^2) + (69/((1-0.3^2))))))

δ = 3.029 mm

The interface deflection can be calculated as:

δi = (P/a) * ((h2 * (E1/((1-v1^2) + (E2/((1-v2^2))))))

Where,

h2 = thickness of the subgrade layer

Substituting the given values in the above formula, we get:

δi = (552/152) * ((0.0 * (345/((1-0.25^2) + (69/((1-0.3^2))))))

δi = 0 mm

As there is no thickness of subgrade layer given, the interface deflection is zero.

The deflection that takes place within the pavement layer can be calculated as the difference between the surface deflection and the interface deflection:

δp = δ - δi

δp = 3.029 - 0

δp = 3.029 mm

Therefore, the surface deflection under the center of a tire is 3.029 mm, the interface deflection is 0 mm, and the deflection that takes place within the pavement layer is 3.029 mm.

The Tariff can be called the custom duty tax. This tax is levied on customers when they have been crossed the good from the national boundaries.

Explanation:

The words called custom, duty is used with tariff services. The tariff is laid on people because to save the domestic product or to raise the revenue. The tariff is firstly used to protect the product and then maybe to yield the revenue.

The domestic products bear tariffs if the goods are equal to the tariff or the foreign brands bear the tariff if the tariff is equal to the products. Then the duty will be equal and beneficial for both services.

The tariff has been classified into three categories such as:

Based on the code given , the Step 1  is done by enforcing maximum() and min() in ARM7 assembly while Step 2  is done by enforcing the main while circle in ARM7 assembly.

To apply the maximum() and min() functions in ARM7 assembly, we can use some instructions to optimize the law and code speed. There is one possible way to do it based on the image attached.

Therefore, To apply the main while loop, we need to check if the left over of the division between result and d isn't zero, and if so, add c to affect. We can use the SWI 0x6 instruction to gain the balance of the division.

See text below

We will translate the following C function, which calculates the Lowest Common Multiple (1cm) between two positive numbers, into ARM7 assembly:

unsigned int lcm(unsigned int a, unsigned int b)

{

(unsigned int c, d, result; // cannot be translated)

c = max(a, b); // i.e. c-a if a >= b, otherwise c=b d = min(a, b); // same, but vice-versa

result = c;

while ((result % d) != 0) {

}

result = result + c;

}

(return(result);

// cannot be translated)

In doing so, you are asked to optimize the assembly code for execution speed. i.e., a) fewest number of cycles, taking into account pipeline emptying/refilling on branch instructions for example, and b) fewest number of instructions.

Disregard the first/last lines of the lcm() function, which cannot be translated into assembly. This exercise is broken into these two steps:

1. First, implement the two successive lines min() and max() in ARM7 assembly:

c = max(a, b); // i.e. c-a if a>=b, otherwise c=b

d = min(a, b); // same, but vice-versa

[Hint 1]: Remember that the function's arguments, a and b, will be found in registers r0 and rl respectively. Every other register is free for you to use in your code. Remember to use conditional instructions whenever possible, to optimize code density and execution speed.

2. Implement the main while loop in ARM7 assembly.

[Hint 2]: The remainder of a division (i.e., the “modulo” operation %) can be obtained by relying on the BIOS, using the ARM7 instruction: SWI 0x6 (which cannot be conditional) after placing the input in the appropriate, predefined registers (see lecture notes), which cannot be selected/changed, and reading the output from the appropriate register.

Both technicians are correct in their respective statements about the causes of low and high line pressures in a transmission system. It is essential to regularly maintain the transmission, including checking and cleaning the vent and filter, to ensure optimal performance and avoid potential problems.

Technician A and Technician B both present plausible causes for transmission issues, but they address different aspects. Technician A is correct in stating that low line pressure can be caused by a plugged transmission vent. A blocked vent can lead to the buildup of pressure inside the transmission, resulting in low line pressure as the transmission cannot maintain the necessary fluid flow for proper functioning. This can cause problems such as erratic shifting, slipping, or overheating.

On the other hand, Technician B is correct in asserting that high line pressure can be caused by a restricted filter. A clogged or restricted transmission filter can obstruct the flow of transmission fluid, leading to increased pressure within the transmission system. This high line pressure can cause harsh shifts, delayed engagement, or even transmission damage over time.

Answer:

It only detects errors if an odd number of bit flips have occurred.

Explanation:

Parity is a measure of how even or odd a string of digits (for example, a string of binary units is).  It is obtained by calculating the value of all the bits. Parity is used in error detection. A parity error is detected when the parity and the odd number of bits are incorrectly propagated.

A problem commonly associated with the parity bits is that they can only detect an odd number of bit errors. This means that if a digit is corrupted in the even binary digits there would be an incorrect detection of errors.

The capacitive reactance of a DC series circuit increases when its capacitance decreases and vice-versa.

A DC series circuit can be defined as a type of circuit in which all of its resistive components are connected end to end, so as to form a single path for the flow of current.

This ultimately implies that, the same amount of current flows through a direct current (DC) series circuit.

Mathematically, the capacitive reactance of a DC series circuit is given by this formula:

\(X_C = \frac{1}{2\pi fC}\)

Where:

From the above formula, we can deduce that the capacitive reactance of a DC series circuit is inversely proportional to both frequency and capacitance. Thus, the capacitive reactance of a DC series circuit increases when its capacitance decreases and vice-versa.

In conclusion, a capacitor would influence a simple DC series circuit by blocking the flow of direct current (DC) through it.

The statement is False. A 257-bit encryption key is not twice as difficult to guess compared to a 256-bit encryption key Encryption keys are used to secure and protect data transmissions and to ensure that only authorized users have access to the data.

The strength of an encryption key is determined by its length, which is measured in bits. The longer the key, the more secure it is and the harder it is to guess or crack. A 256-bit encryption key is already considered extremely secure, and increasing the length of the key even by one bit can significantly increase its strength.

However, increasing the key length from 256 bits to 257 bits does not double its strength. In fact, the increase in strength is much less significant than that. It is difficult to compare the exact level of difficulty in guessing an encryption key of a particular length, as it depends on several factors such as the encryption algorithm being used and the resources available to the attacker.

Explanation:

To prove that a red-black tree with n internal nodes will have a height of at most 2log₂(n+1), we need to use the properties of red-black trees and induction.

Base Case: For n = 1, the tree has only one internal node. In this case, the height of the tree is 1, which satisfies the inequality 2log₂(1+1) = 2.

Inductive Step: Assume that for any red-black tree with k internal nodes, the height is at most 2log₂(k+1). Now, let's consider a red-black tree with n internal nodes.Since a red-black tree is a binary search tree, it follows the property that the number of internal nodes in the left subtree plus the number of internal nodes in the right subtree, plus one for the root, is equal to the total number of internal nodes in the tree. Therefore, we can conclude that at least one of the subtrees must have at least n/2 internal nodes.

By the induction hypothesis, the height of the subtree with at least n/2 internal nodes is at most 2log₂((n/2)+1). Using logarithmic properties, we can rewrite this as 2(log₂(n/2) + log₂(2)). Simplifying further, we get 2(log₂(n) - 1 + 1) = 2log₂(n).

Since the height of the subtree is at most 2log₂(n), the overall height of the red-black tree is also at most 2log₂(n).

Thus, we have proven that for a red-black tree with n internal nodes, the height of the tree is at most 2log₂(n+1).

Solving this equation will give us the value of t at which the velocity reaches 27 mm/s.

Given:

v = k√s

Integrating both sides with respect to s:

∫(1/v) dv = ∫(k√s) ds

ln|v| = (2/3)k(s^(3/2)) + C1

Taking the exponential of both sides:

|v| = e^[(2/3)k(s^(3/2)) + C1]

Since v is positive, we can remove the absolute value:

v = e^[(2/3)k(s^(3/2)) + C1]

Now, we need to find the constant C1. We know that v = v0 when t = 0:

v0 = e^[(2/3)k(s0^(3/2)) + C1]

Since v0 = 6 mm/s, we can rewrite the equation as:

6 = e^[(2/3)k(s0^(3/2)) + C1] ---- (1)

Next, to find the position as a function of time, we need to solve for s in terms of t. We can use the relationship v = ds/dt:

ds/dt = k√s

Rearranging the equation and integrating both sides with respect to t:

∫(1/√s) ds = ∫k dt

2√s = kt + C2

√s = (kt/2) + C2

Squaring both sides:

s = (k^2t^2/4) + C2kt + C2^2

Now, we need to find the constants C2. We know that s = s0 when t = 0:

s0 = (k^2(0)^2/4) + C2(0) + C2^2

Since s0 is the initial position, we can rewrite the equation as:

s0 = C2^2 ---- (2)

Now, let's evaluate the time t, position s, and acceleration a when the velocity reaches 27 mm/s. From equation (1), we have:

27 = e^[(2/3)k(s^(3/2)) + C1]

Substituting the expression for s from equation (2), we have:

27 = e^[(2/3)k(C2^(3/2)) + C1]

Solving this equation will give us the value of t at which the velocity reaches 27 mm/s.
