This question is incomplete, the complete question is;

For a steel alloy it has been determined that a carburizing heat treatment of 11.3 h duration at Temperature T1 will raise the carbon concentration to 0.44 wt% at a point 1.8 mm from the surface. A separate experiment is performed at T2 that doubles the diffusion coefficient for carbon in steel.

Estimate the time necessary to achieve the same concentration at a 4.9 mm position for an identical steel and at the same carburizing temperature T2.

Answer:

the required time to achieve the same concentration at a 4.9 is 83.733 hrs

Explanation:

Given the data in the question;

treatment time t₁ = 11.3 hours

Carbon concentration = 0.444 wt%

thickness at surface x₁ = 1.8 mm = 0.0018 m

thickness at identical steel x₂ = 4.9 mm = 0.0049 m

Now, Using Fick's second law inform of diffusion

\(x^2\) / Dt = constant

where D is constant

then

\(x^2\) / t = constant

\(x^2_1\) / t₁ = \(x^2_2\) / t₂

\(x^2_1\) t₂ = t₁\(x^2_2\)

t₂ = t₁\(x^2_2\) / \(x^2_1\)

t₂ = (\(x^2_2\) / \(x^2_1\))t₁

t₂ = \((\) \(x_2\) / \(x_1\) \()^2\) × t₁

so we substitute

t₂ = \((\) 0.0049  / 0.0018  \()^2\) × 11.3 hrs

t₂ = 7.41 × 11.3 hrs

t₂ = 83.733 hrs

Therefore, the required time to achieve the same concentration at a 4.9 is 83.733 hrs

The heat transfer rate is 0.569 kW.

To determine the rate of heat transfer in this situation, we need to calculate the energy required to boil the water. This can be calculated using the following equation:

Energy = Mass x Specific Heat Capacity x Temperature Change

The mass of water in the pan can be calculated using the following equation:

Mass = Density x Volume

Using the values given, we get:

Mass = 1000 kg/m3 x (π x (0.307 m)2 x 1.85 cm) = 0.0256 kg

The specific heat capacity of water is 4.184 kJ/kgK. Therefore, the total energy required to boil the water is:

Energy = 0.0256 kg x 4.184 kJ/kgK x (100°C - 20°C) = 8.3 kJ

The rate of heat transfer can be calculated by dividing the total energy by the time taken:

Rate of Heat Transfer = 8.3 kJ / 14.6 min = 0.569 kW

The correct answer is I mentioned earlier, the question lacks specific information that is needed to provide a precise answer. The number of millimeters indicated by a Vernier caliper will depend on the position of the sliding scale and the Vernier scale relative to the object being measured.

To use a Vernier caliper, the object being measured is placed between the jaws of the caliper, and the position of the sliding scale is adjusted until it touches the object being measured. The position of the sliding scale is then read off the main scale in millimeters, and the position of the Vernier scale is read off the Vernier scale. The difference between the main scale reading and the Vernier scale reading gives the measurement to the nearest fraction of a millimeter. Therefore, without specific information about the position of the sliding scale and Vernier scale relative to the object being measured, it is impossible to provide a specific answer. If you can provide more information, such as the position of the sliding and Vernier scales, I may be able to give you a more precise answer.

Answer:

The work transfer per unit mass is approximately 149.89 kJ

The heat transfer for an adiabatic process = 0

Explanation:

The given information are;

P₁ = 1 atm

T₁ = 70°F = 294.2611 F

P₂ = 5 atm

γ = 1.5

Therefore, we have for adiabatic system under compression

\(T_{2} = T_{1}\cdot \left (\dfrac{P_{2}}{P_{1}} \right )^{\dfrac{\gamma -1}{\gamma }}\)

Therefore, we have;

\(T_{2} = 294.2611 \times \left (\dfrac{5}{1} \right )^{\dfrac{1.5 -1}{1.5 }} \approx 503.179 \ K\)

The p·dV work is given as follows;

\(p \cdot dV = m \cdot c_v \cdot (T_2 - T_1)\)

Therefore, we have;

Taking air as a diatomic gas, we have;

\(C_v = \dfrac{5\times R}{2} = \dfrac{5\times 8.314}{2} = 20.785 \ J/(mol \cdot K)\)

The molar mass of air = 28.97 g/mol

Therefore, we have

\(c_v = \dfrac{C_v}{Molar \ mass} = \dfrac{20.785}{28.97} \approx 0.7175 \ kJ/(kg \cdot K)\)

The work done per unit mass of gas is therefore;

\(p \cdot dV =W = 1 \times 0.7175 \times (503.179 - 294.2611) \approx 149.89 \ kJ\)

The work transfer per unit mass ≈ 149.89 kJ

The heat transfer for an adiabatic process = 0.

Explanation:

At its maximum no-load speed, an engine may hunt and surge due to a blocked carburetor bowl vent.

An engine or motor is a device designed to convert electrical energy from one or more sources into mechanical energy.

Currently available energy sources include potential energy, heat energy, chemical energy, electric potential, nuclear energy, and energy from the Earth's gravitational field (from nuclear fission or nuclear fusion).

Since many of these processes require heat as an intermediary energy source, heat engines are particularly crucial.

One instance of a natural process that converts environmental heat into motion is atmospheric convection cells (e.g. in the form of rising air currents).

Mechanical energy is essential for transportation in addition to participating in many industrial operations like cutting, grinding, crushing, and mixing.

In programming, passing an argument to a function can be done by value or by reference. When an argument is passed by value, a copy of its value is made and passed to the function.

This means that any changes made to the value within the function do not affect the original argument. On the other hand, when an argument is passed by reference, a reference to the original argument is passed to the function.

This allows the function to directly modify the original argument. In order for a function to change the value of an original argument, it needs to be passed into a reference parameter.

Answer:

a. 20.265 MN

b. 0.555 MNm

c. 403.44 KW

Explanation:

Given:-

- The width ( w ) = 1000 mm

- Original thickness ( to ) = 10 mm

- Final thickness ( t ) = 5 mm

- The radius of the rollers ( R ) = 600 mm

- The peripheral speed of the roller ( v ) = 0.12

- Deformation efficiency ( ε ) = 55%

Find:-

a) the roller force ( F )

b) the roller torque ( T )

c) the performance on the pair of rollers. ( P )

Solution:-

- The process of flat rolling entails a pair of compressive forces ( F ) exerted by the rollers on the steel sheet that permanently deforms.

- The permanent deformation of sheet metal is seen as reduced thickness.

- We will assume that the compressive force ( F ) acts normal to the point of contact between rollers and metal sheet.

- The roll force ( F ) is defined as:

                                 \(F =L*w*Y_a_v_g\)

Where,

                     L: The projected length of strip under compression

                     Y_avg: The yielding stress of the material = 370 MPa

- The projected length of strip under compression is approximated by the following relation:

                               \(L = \sqrt{R*( t_o - t_f )} \\\\L = \sqrt{0.6*( 0.01 - 0.005 )} \\\\L = 0.05477 m\)

- The Roll force ( F ) can be determined as follows:

                            \(F = (0.05477)*(1 )*(370*10^6 )\\\\F = 20.265 MN\)

- The roll torque ( T ) is given by the following relation as follows:

                               \(T = \frac{L}{2} * F\\\\T = \frac{0.05477}{2} * 20.265\\\\T = 0.555 MNm\)

- The rotational speed of the rollers ( N ) is determined by the following procedure:

                               \(f = \frac{v}{2\pi* R} = \frac{0.12}{2*\pi 0.6} = 0.03181818 \frac{rev}{s} \\\\N = f*60 = 1.9090 rpm\)

- The power consumed by the pair of rollers ( P ) is given by:

                              \(P = \frac{2\pi * F * L * N}{e*60,000} KW \\\\P = \frac{2\pi * ( 20.265*10^6) * (0.05477) * (1.90909 ) }{60,000*0.55} KW\\\\P = 403.44 KW\)
