The land on which the pond would be placed is a square. The formula for determining the area of a square is expressed as

Area = L²

The length of a side of the square is 2x. This means that the area of the land would be

Area = (2x)² = 4x²

The pond is circular and the formula for determining the area of a circle is

Area = πr²

Where

π is a constant

The radius of the pond is x. Therefore, area covered by the pond is

Area = π × x² = πx²

The part of the square not covered by the pond will be planted with flowers. Therefore, the area of the region that will be planted with flowers is

For the parallel fillet weld, the length required is 24.52mm and for transverse fillet welds, the longer fillet weld required is 24.39 mm and the length of the shorter fillet weld required is 6.13 mm.

The length of weld required to transmit a load between two plates depends on the type of weld used and the strength of the material being welded. For the given scenario:

Two parallel fillet welds:

The length of each fillet weld required can be calculated using the following formula:

L = (2 x F x P) / (0.7 x T)

where L is the length of each fillet weld, F is the applied force (54.5 KN), P is the perimeter of the weld (2 x length of the joint), T is the thickness of the plate (12.7 mm), and 0.7 is a constant. Substituting the values, we get:

L = (2 x 54.5 x 2) / (0.7 x 12.7) = 24.52 mm

Therefore, the length of each fillet weld required is 24.52 mm.

Two transverse fillet welds:

The length of each fillet weld required in this case can be calculated using the same formula as above, but with the perimeter of the weld being the sum of the lengths of the two sides being welded. Since the two fillet welds are transverse, their lengths will be different. Assuming one fillet weld is longer than the other, we can calculate their lengths as follows:

L1 = (F x P1) / (0.7 x T)

L2 = (F x P2) / (0.7 x T)

where L1 and L2 are the lengths of the two fillet welds, P1 and P2 are the perimeters of the two sides being welded, and all other variables are the same as before. We can assume that the longer fillet weld is on the side with the higher applied force, so we have:

P1 = 2 x length of joint

P2 = length of joint

Substituting the values, we get:

L1 = (54.5 x 2 x 2) / (0.7 x 12.7) = 24.39 mm

L2 = (54.5 x 1) / (0.7 x 12.7) = 6.13 mm

Therefore, the length of the longer fillet weld required is 24.39 mm and the length of the shorter fillet weld required is 6.13 mm.

To modify the program to pass the variable `x` by reference using pointers, we need to change the `square` function to take a pointer parameter.

By dereferencing the pointer and updating the value at the memory address it points to, we can modify the original variable `x`. This ensures that `x` is squared within the `square` function.

Modified code:

```c

#include <stdio.h>

void square(int* num) {

   *num = (*num) * (*num);

}

int main() {

   int x = 4;

   square(&x);

   printf("%d\n", x);

   return 0;

}

```

In the modified code, the `square` function is modified to take an `int*` parameter instead of an `int` parameter. This indicates that it expects a pointer to an integer. Inside the function, we dereference the pointer using the `*` operator and perform the square operation on the value it points to. This updates the original variable `x` in the `main` function.

In the `main` function, when calling `square`, we pass the address of `x` using the `&` operator. This allows the `square` function to directly modify the value of `x` at that memory address.

As a result, when we print the value of `x` after calling `square`, it will be the squared value (16 in this case) instead of the original value (4).

m(u4 - u3) + P(V4 - V3) is heat transfer for processes where m is the mass of the air, u is the internal energy, P is the pressure, and V is the volume.

To plot the cycle on P-v and T-s diagrams, we can begin by drawing four points representing the four states of the system: 1, 2, 3, and 4. We can then connect these points in the order that the processes occur, using lines of constant temperature and pressure as appropriate.

On the P-v diagram, we can plot the four states as follows:

State 1: P1 = 1 bar, v1 = v(T1, P1)

State 2: P2 = 10 bar, v2 = v(T1, P2)

State 3: P3 = 10 bar, v3 = v(T3, P3)

State 4: P4 = 1 bar, v4 = v(T4, P4)

We can then connect these points with lines of constant temperature (for processes 1 to 2 and 3 to 4) and constant pressure (for processes 2 to 3 and 4 to 1). The process directions can be indicated with arrows.

On the T-s diagram, we can plot the four states as follows:

State 1: T1 = 300 K, s1 = s(T1, P1)

State 2: T2 = T1 = 300 K, s2 = s(T2, P2)

State 3: T3 = 1500 K, s3 = s(T3, P3)

State 4: T4 = T3 = 1500 K, s4 = s(T4, P4)

We can then connect these points with lines of constant pressure (for processes 1 to 2 and 3 to 4) and constant temperature (for processes 2 to 3 and 4 to 1). The process directions can be indicated with arrows.

(b) To calculate the specific heat transfer for processes 1 to 2 and 3 to 4, we can use the first law of thermodynamics:

ΔQ = ΔU + Δ(PV)

For process 1 to 2, we can write:

ΔQ12 = ΔU12 + Δ(PV)12

= m(u2 - u1) + P(V2 - V1)

For process 3 to 4, we can write:

ΔQ34 = ΔU34 + Δ(PV)34

= m(u4 - u3) + P(V4 - V3)

where m is the mass of the air, u is the internal energy, P is the pressure, and V is the volume.

(c) To determine the thermal efficiency of the cycle, we can use the definition of thermal efficiency:

η = Wcycle / Qin

where Wcycle is the work done by the system during the cycle, and Qin is the heat transfer into the system during the cycle.

For this cycle, we can write:

Wcycle = P(V2 - V1) + P(V4 - V3)

= P(V2 + V4 - V1 - V3)

Qin = Q12 + Q34

= -Q12 - Q34

Substituting these expressions into the definition of thermal efficiency, we get:

η = (P(V2 + V4 - V1 - V3)) / (-Q12 - Q34)

The ideal Otto cycle has a higher thermal efficiency than an actual internal combustion engine due to the limitations of real-world components and the environment. The power output of the two cycles remains the same, however the actual internal combustion engine requires more energy to run at the same power output. This is because actual internal combustion engines have higher pressure drops, incomplete combustion, friction, and heat losses that are not present in the ideal cycle.

The actual internal combustion engine cycle Otto thermal efficiency differs from the ideal one at the same power output. Below are the differences: Actual internal combustion engine cycle Otto thermal efficiency and ideal one at the same power output The actual internal combustion engine cycle Otto thermal efficiency differs from the ideal one at the same power output. The reasons are given below: In the internal combustion engine cycle, the fuel combustion process is not always perfect, and in some instances, incomplete combustion may occur. As a result, the fuel does not combust completely, and a portion of the energy is wasted as waste heat. Because of this waste, the actual thermal efficiency of the engine is decreased. On the other hand, in an ideal Otto cycle, the combustion process is 100% efficient, resulting in no waste heat. As a result, the thermal efficiency of an ideal Otto cycle is greater than that of an actual cycle.

Otto Cycle

The Otto Cycle, which was developed in 1876 by German engineer Nicolaus Otto, is the most widely used internal combustion cycle for gasoline engines. It is a theoretical cycle that is not perfectly efficient, but it is often used as a standard to compare other engines with. In a four-stroke engine, the Otto cycle is employed to power the vehicle. It consists of four strokes: intake, compression, power, and exhaust. The cycle is theoretical because it assumes ideal conditions.

The efficiency of an internal combustion engine can be improved by increasing the engine compression ratio, which results in more fuel burning and less energy waste.

The values of h at the two internal boundaries are :

Given data :

Z₁ = Z₂ = Z₃ = 25 m

h top = 120 m

h bottom = 100 m

K₁ = 0.0001 m/s

K₂ = 0.0005 m/s

K₃ = 0.0010 m/s

we will apply the formula below since flow is perpendicular to the bedding plane

Keq = \(\frac{Z1 + Z2 + Z3 }{\frac{Z1}{K1}+\frac{Z2}{K2} + \frac{Z3}{K3} }\)  ----- ( 1 )

Insert values given above into equation 1

Therefore ; Keq = 2.307 * 10⁻⁴ m/s

Hydraulic gradient ( Ieq ) = head loss / length

                                          = ( 120 - 100 ) / 3 * 25

                                   Ieq  = 0.266

Given that the flow is perpendicular to bedding plane

q1 = q2 = q3

V₁ = V₂ = V₃ = V

K₁i₁ = K₂i₂ = K₃i₃ = Keq * ieq

Hence :

V = Keq* Ieq

   = 2.307 * 10⁻⁴ * 0.266

   = 6.15 * 10⁻⁵ m/s .

Also;

K₁i₁ =  Keq * ieq = K₂i₂ = K₃i₃

therefore :

  i₁ = 0.615

  i₂ =  0.123

  i₃ = 0.0615

Pressure at point 1 ( i.e. pressure between first two formations )

h₁ = h top - i₁L₁

   = 120 - 0.615 * 25

   = 104.625 m

Pressure at point 2 ( i.e. pressure between the 2nd and 3rd formation )

h₂ = h₁ - i₂L₂

    = 104.625 - 0.123 * 25

    = 101.55 m

Therefore we can conclude that The values of h at the two internal boundaries are :  h₁ = 104.625 m , h₂ = 101.55 m

Answer: The 8-core machine saves  87.5% of the dynamic power.

Explanation:

Let Fold = f , Vold = V , Cold = Capacitance

so

Old Dynamic power = Cold × (Vold × Vold) × f

therefore for the 8-core machine

 Fnew / Fold = 1/4

Fnew = Fold/4

we were told that Voltage decreases proportional to frequency,

so

Vnew / Vold = 1/4

Vnew = V / 4

So New Capacitance will be;

Cnew = Cold

Thus, New Dynamic power = 8 × Cnew × ( Vnew × Vnew ) ×  Fnew

= 8 × Cold × (Vold × Vold/16) × ( f/4 )

=  8 × ( Cold ) × ( Vold × Vold ) × ( f ) / 64

= (Old Dynamic Power) / 8

therefore

Old Dynamic Power / New Dynamic Power = 8

Thus, Percentage of power saved will be;

Percentage power saved = 100 × ( Old Dynamic Power - New Dynamic Power ) / Old Dynamic Power

=   100 × (8-1) / 8

= 87.5 %

Therefore The 8-core machine saves  87.5% of the dynamic power.

b) (b) Four types of internal combustion engine includes;

1) The diesel engine

2) The Otto engine

3) The Brayton engine

4) The Wankel engine

Explanation:

The parameters of the Otto cycle are;

The heat added, \(Q_{in}\) = 2,800 kJ/kg

The compression ratio, r = 8

The beginning compression pressure, P₁ = 1 bar

The beginning compression temperature, T₁ = 300 K

Cp = 1.005 kJ/kg·K

Cv = 0.718 kJ/kg·K

R = 287 kJ/kg·K

K = Cp/Cv = 1.005 kJ/kg·K/(0.718 kJ/kg·K) ≈ 1.4

T₂ = T₁×r^(k - 1)

∴ T₂ = 300 K×8^(1.4 - 1) ≈ 689.219 K

\(\dfrac{P_1\cdot V_1}{T_1} = \dfrac{P_2\cdot V_2}{T_2}\)

\(P_2 = \dfrac{P_1\cdot V_1 \cdot T_2}{T_1 \cdot V_2} = \dfrac{V_1}{V_2} \cdot \dfrac{P_1 \cdot T_2}{T_1 } = r \cdot \dfrac{P_1 \cdot T_2}{T_1 }\)

∴ P₂ = 8 × 1 bar × (689.219K)/300 K ≈ 18.379 bar

\(Q_{in}\) = m·Cv·(T₃ - T₂)

∴ \(Q_{in}\) = 2,800 ≈ 0.718 × (T₃ - 689.219)

T₃ = 2,800/0.718 + 689.219 = 4588.94 K

P₃ = P₂ × (T₃/T₂)

P₃ = 18.379 bar × 4588.94K/(689.219 K) = 122.37 bar

The maximum pressure = P₃ ≈ 122.37 bar

(ii) The thermal efficiency, \(\eta_{Otto}\), is given as follows;

\(\eta_{Otto} = 1 - \dfrac{1}{r^{k - 1}}\)

Therefore, we have;

\(\eta_{Otto} = 1 - \dfrac{1}{8^{1.4 - 1}} \approx 0.5647\)

The thermal efficiency, \(\eta_{Otto}\) ≈ 0.5647

Therefore, the thermal efficiency ≈ 56.47%

(iii) The mean effective pressure, MEP is given as follows;

\(MEP = \dfrac{\left(P_3 - P_1 \cdot r^k \right) \cdot \left(1 - \dfrac{1}{r^{k-1}} \right)}{(k -1)\cdot (r - 1)}\)

Therefore, we get;

\(MEP = \dfrac{\left(122.37 - 1 \times 8^{1.4} \right) \cdot \left(1 - \dfrac{1}{8^{1.4-1}} \right)}{(1.4 -1)\cdot (8 - 1)} \approx 20.974\)

The mean effective pressure, MEP ≈ 20.974 bar
