The selection of shaft keys is critical in preventing premature failure of keyed joints. Shaft keyways and keys are used to transmit torque from shafts to mechanical transmission elements such as gears, pulleys, and so on.

A key to preventing early failure of keyed joints is choosing the right shaft key. The use of a keyed joint allows for the transmission of torque from shafts to mechanical transmission components like gears, pulleys, etc. They can be produced using a standard stock material, like key stock, or they can be specially machined to fit the application.

According to various standards like BS4235, the nominal shaft diameter is typically used to specify the key size, and the commonly accessible rectangular key is used for the majority of applications. As a result, the standards do not specify the key material or joint limitations, and a keyed joint is oversized to support all loads.

There are four main groups of shaft keys:

Stainless steel or medium carbon steel are typically used to make shaft keys. To suit various application environments, they can be made from a wide variety of materials, including bronze, copper, brass, and aluminum alloy. For example, stainless steel grade for use in food service equipment and brass or bronze keys for marine propeller shafts.

Key steel is typically supplied in accordance with BS46 and BS4235 and is a medium carbon steel that is unalloyed and has a respectable tensile strength. Due to their ideal blend of strength, toughness, and favorable machining properties, unalloyed medium carbon steels with carbon contents ranging from 0.25% to 0.60% are used.

Answer:

The equilibrium temperature is 109.7°C

The total entropy change for the process is 0.23 kJ/K

Explanation:

The parameters given are;

The initial temperature of aluminium, T₁ₐ = 140°C = 413.15 K

Mass, m₁, of aluminium block = 28 kg

The specific heat of aluminium, c₁, at 400 K = 0.949 kJ/(kg·K)

The initial temperature of iron, T₁ₙ = 60°C = 333.15 K

Mass, m₂, of iron block = 36 kg

The specific heat of iron, c₂, at room temperature = 0.45 kJ/(kg·K)

The heat lost by the aluminium = Heat gained by the iron

The heat lost by the aluminium = m₁ × c₁ × (T₁ₐ - Tₓ)

The heat lost by the aluminium = 28 × 0.949 × (413.15 - Tₓ)

The heat gained by the iron =  m₂ × c₂ × (Tₓ - T₁ₙ)

The heat gained by the iron =  36 × 0.45 × (Tₓ - 333.15)

Hence;

28 × 0.949 × (413.15 - Tₓ) = 36 × 0.45 × (Tₓ - 333.15)

26.572 × (413.15 - Tₓ) = 16.2 × (Tₓ - 333.15)

∴ (26.572 + 16.2) × Tₓ = 26.572 × 413.15 + 16.2 × 333.15

42.772·Tₓ = 16375.2518

Tₓ = 382.85 K = 109.7°C

The total entropy change of the process is given by the following relation;

\(\Delta S = \Delta S_{Fe} + \Delta S_{Al}\)

\(=m_{1}c_{1}ln\dfrac{T_{x}}{T_{1n}}+m_{2}c_{2}ln\dfrac{T_{x}}{T_{1a}}\)

\(=28 \times 0.949 \times ln\dfrac{382.85}{413.15}+36 \times 0.45 \times ln\dfrac{382.85}{333.15} = 0.23 \, \dfrac{kJ}{K}\)

The correct answer is that both technician A and technician B are correct. Let's explore why both of them are correct.Technician A is correct in saying that a properly filled cooling system is necessary for the correct function of an ECT sensor.

When the engine coolant is low, the ECT sensor may not have enough coolant flowing around it to read the temperature accurately. If the cooling system is not filled to the proper level, the ECT sensor reading could be affected. So, Technician A is correct.Technician B is correct in saying that the voltage measured on the ECT signal wire should be low when the engine is cold and high when the engine is hot.

When the engine is cold, the voltage measured on the ECT signal wire will be low because the resistance in the sensor is high. As the engine warms up, the resistance in the ECT sensor decreases, causing the voltage on the signal wire to increase. The voltage measured on the ECT signal wire should be proportional to the engine temperature, so Technician B is also correct.In conclusion, both Technician A and Technician B are correct in their statements.

a. use the one prime factor(N) routine to find a prime factor p of N. b .the algorithm will call the one prime factor(N) routine approximately n/2 times. c. this has a worst-case time complexity of O(n log n). time complexity of O(2^(n/2)), d. this algorithm is definitely an improvement.

Binary numbers are a number system that only uses two digits, 0 and 1, to represent numbers. In the binary system, each digit represents a power of two, with the rightmost digit representing 2^0 (1), the next digit representing 2^1 (2), the next digit representing 2^2 (4), and so on.

For example, the binary number 1010 represents the decimal number (1 x 2^3) + (0 x 2^2) + (1 x 2^1) + (0 x 2^0), or 8 + 0 + 2 + 0, which is equal to 10 in decimal.

(a) We can use the one prime factor(N) routine repeatedly to factor the given n-digit binary number into prime factors. We can repeatedly call the one prime factor(N) routine until we get all the prime factors of the number. After each call, we divide the input number by the prime factor obtained from the routine, and repeat the process until we have obtained all the prime factors.

Here is the pseudocode for the algorithm:

Input: n-digit binary number N

while N > 1:

  factor = one_prime_factor(N)

  print(factor)

  N = N / factor

(b) In the worst case, the input number may be a large prime number. In this case, the one prime factor(N) routine will return the input number itself as the prime factor. Therefore, we will need to call the one prime factor(N) routine n times to factor the input number into primes.

(c) Each call to the one prime factor(N) routine takes O(n^3) time (assuming it takes linear time to perform arithmetic operations on two n-digit binary numbers). Therefore, the worst-case time complexity of the algorithm is O(n^4).

(d) The time complexity of the algorithm is quite high, which means it may not be fast enough for large input sizes. In practice, there are faster algorithms for factoring integers, such as the general number field sieve (GNFS) or the quadratic sieve (QS), which have much lower time complexities. However, the one prime factor(N) routine may still be useful in certain situations where we only need to find one prime factor of a number.

Answer:

If Reynolds number increases the extent of the region around the object that is affected by viscosity decreases.

Explanation:

Reynolds number is an important dimensionless parameter in fluid mechanics.

It is calculated as;

\(R_e__N} = \frac{\rho vd}{\mu}\)

where;

ρ is density

v is velocity

d is diameter

μ is viscosity

All these parameters are important in calculating Reynolds number and understanding of fluid flow over an object.

In aerodynamics, the higher the Reynolds number, the lesser the viscosity plays a role in the flow around the airfoil. As Reynolds number increases, the boundary layer gets thinner, which results in a lower drag. Or simply put, if Reynolds number increases the extent of the region around the object that is affected by viscosity decreases.

To implement a queue class using a singly linked list with no header or tail nodes, certain steps should be followed. Firstly, the list should be initialized, and for a singly linked list, only one variable is needed, which is the first node pointer or the head.

Next, a new node should be set at the tail, and the addition operation should always take place at the tail. The current node at the end of the list should have a next pointer pointing to the new node being added, and the new node should be assigned to the end of the list, which means that the new node should be set as the tail.

Moreover, the head should be established if the list is empty, and in this case, the new node will be both the head and the tail, with its next value being null. At the end of the queue, it is important to modify the last node's next pointer to point to the new node that has been inserted, making it the new last node.

On the other hand, to remove the head, the head node, which has been in the queue the longest, must be removed first. After removing the head node, we must modify the list's head pointer to reflect the next node as the new head. We can use the next pointer of the present head node to obtain the new head node. After getting the new head node, we can subsequently release the memory for the removed head node. This is how it's accomplished.

Finally, it's important to ensure that the head and tail pointers of the list are always maintained. When the last node is removed, the list becomes empty, and the head and tail pointers should be set to null to signify that there is no node in the list.

Explanation:

According to the question, the data is as follows

The Density of water at 20 degrees celcius is 1000 kg/m^3

Viscosity is 0.001kg/m/.s

Velocity V = 25 cm/s

V = 0.25 m/s

Now

a. The creeping motion is

As we know that

Reynold Number = (Density of water × V × d) ÷ (Viscosity)

1 = (1,000 × 0.25 × d) ÷ 0.0001

d = (1 × 0.001) ÷ (1,000 × 0.25)

= 4E - 06^m

= 4\(\mu m\)

b. Now the sphere diameter is

Reynold Number = (Density of water × V × d) ÷ (Viscosity)

250,000 = (1,000 × 0.25 × d) ÷ 0.0001

d = (250,000 × 0.001) ÷ (1,000 × 0.25)

Answer:

A) Power output = 541.67 MW

B) Backwork ratio = 0.4

C) Improved thermal efficiency = 0.598

Explanation:

We are given;

Net power output; W'_net = 325 MW

Minimum Temperature; T1 = 300 K

Maximum Temperature; T4 = 1500 K

Compression Pressure ratio;P2/P1 = 12

From online tables, we have the following properties of air;

Specific heat capacity; C_p = 1.004 KJ/Kg

Adiabatic constant; k = 1.4

Temperature at stage 2 will be given by the formula;

T2 = T1(P2/P1)^((k - 1)/k)

Plugging in the relevant values gives;

T2 = 300(12)^((1.4 - 1)/1.4)

T2 = 610.18 K

Similarly, Temperature at stage 3 will be;

T3 = T4(P2/P1)^((k - 1)/k)

Plugging in the relevant values gives;

T3 = 750(12)^((1.4 - 1)/1.4)

T3 = 1525.45 K

Now, let's calculate the specific heat addition given by the formula;

q = C_p(T3 - T2)

q = 1.004(1525.45 - 610.18)

q = 918.93 KJ/Kg

Let's now calculate the specific net work output;

w_net = C_p[(T3 - T4) - (T2 - T1)]

w_net = 1.004[(1525.45 - 750) - (610.18 - 300)]

w_net = 467.13 KJ/Kg

A) Power output is given by;

W_T = (W'_net/W_net) × C_p(T3 - T4)

W_T = (325/467.13) × 1.004(1525.45 - 750)

W_T = 541.67 MW

B) back work ratio is;

f = (T2 - T1)/(T3 - T4)

f = (610.18 - 300)/(1525.45 - 750)

f = 0.4

C) Thermal efficiency is given by;

η = w_net/q

Since we are told that a regenerator, with an effectiveness of 85 percent, were installed in the power plant.

Thus;

η = (w_net/q)÷0.85

η = (467.13/918.94) ÷ 0.85

η = 0.598

La diferencia media logarítimica de temperatura del intercambiador en paralelo es aproximadamente 75.466 ºC.

La diferencia media logarítmica de temperatura del intercambiador en contracorriente es aproximadamente 97.881 ºC.

Explanation:

De la teoría de Transferencia de Calor tenemos que un intercambiador de calor en paralelo presenta las siguientes dos características:

1) Tanto el fluido caliente como el fluido frío entran por el mismo lado.

2) Tanto el fluido caliente como el fluido frío salen por el mismo lado.

Mientras que el intercambiador de calor en contracorriente tiene que:

1) El fluido caliente y el fluido frío entran por lados opuestos.

2) El fluido caliente y el fluido frío salen por lados opuestos.

A continuación, anexamos los esquemas de perfil de cada intercambiador.

Ahora, la Diferencia Media Logarítimica de Temperatura (\(\Delta T_{lm}\)), medida en grados Celsius, queda definida como sigue:

\(\Delta T_{lm} = \frac{\Delta T_{1}-\Delta T_{2}}{\ln \frac{\Delta T_{1}}{\Delta T_{2}} }\) (Eq. 1)

Donde \(\Delta T_{1}\) y \(\Delta T_{2}\) son las diferencias de temperatura de los fluidos en cada extremo del intercambiador, medido en grados Celsius.

Procedemos a determinar esas diferencias y la Diferencia Media Logarítimica de Temperatura para cada configuración:

Intercambiador en paralelo

\(\Delta T_{1} = 180\,^{\circ}C-3\,^{\circ}C\)

\(\Delta T_{1} = 177\,^{\circ}C\)

\(\Delta T_{2} = 78\,^{\circ}C - 55\,^{\circ}C\)

\(\Delta T_{2} = 23\,^{\circ}C\)

\(\Delta T_{lm} = \frac{177\,^{\circ}C-23\,^{\circ}C}{\ln \frac{177\,^{\circ}C}{23\,^{\circ}C} }\)

\(\Delta T_{lm} \approx 75.466\,^{\circ}C\)

La diferencia media logarítimica de temperatura del intercambiador en paralelo es aproximadamente 75.466 ºC.

Intercambiador en contracorriente

\(\Delta T_{1} = 180\,^{\circ}C-55\,^{\circ}C\)

\(\Delta T_{1} = 125\,^{\circ}C\)

\(\Delta T_{2} = 78\,^{\circ}C-3\,^{\circ}C\)

\(\Delta T_{2} = 75\,^{\circ}C\)

\(\Delta T_{lm} = \frac{125\,^{\circ}C-75\,^{\circ}C}{\ln \frac{125\,^{\circ}C}{75\,^{\circ}C} }\)

\(\Delta T_{lm} \approx 97.881\,^{\circ}C\)

La diferencia media logarítmica de temperatura del intercambiador en contracorriente es aproximadamente 97.881 ºC.
