A petrochemical plant in Island C produces formaldehyde (CH2O) industrially by the

catalytic oxidation of methanol (CH3OH). The following is the chemical reaction:

CH3OH + ½O2 → CH2O + H2O --- (1)

Unfortunately, a significant portion of the formaldehyde will react with oxygen to produce CO

and H2O. The following is the side reaction:

The torque converter is used in CVTs to transmit engine output. The torque converter, which functions like a clutch and is equipped with an ATF, is a crucial component of the vehicle for boosting torque and transmitting significant kinetic force during taking off.

Modern torque-converter autos are pushing as high as nine gears, modern twin-clutch systems have seven gears, and CVTs can create nearly unlimited ratios, making them the most fuel-efficient. Automatic transmissions can shift faster than the fastest manual drivers, but they can't accelerate as quickly.

One of the most crucial and underappreciated components of the car is the torque converter. It is essential to the operation of automatic transmission vehicles and plays a significant role in determining your fuel efficiency.

Explanation:

The heat flux is =1038kW/m² , the heat lost per hour is =259.5 kW, the heat lost per hour using a sheet of soda- lime glass.

The thickness of steel( t) = 10mm = 10× 10^-³m

The temperature difference on both sides = 300-100

∆T = 200°C

But the formula for heat flux = q = k∆T/t

Where K = thermal conductivity for steel = 51.9W/mK.

Substitute the variables into the formula for heat flux;

q = 51.9 × 200/10 × 10-³

q = 10380 × 10³/10

q = 10380000/10

q = 1038000 W/m² = 1038kW/m²

To calculate the heat lost per hour if the cross sectional area is = 0.25 m2 use the formula q × A

Explanation:

Assuming the word "allowed" was meant to be "alloyed"

The reactions at supports A, B, and C can be determined by analyzing the equilibrium of forces and moments acting on the structure.

To determine the reactions at supports A, B, and C, we need to consider the equilibrium of forces and moments.

Let's assume the structure is a beam supported by three points: A, B, and C.

1. Support A: Since support A is a roller support, it can only exert a vertical reaction. The reaction at support A can be determined by summing up the vertical forces acting on the beam.

2. Support B: Support B is a fixed support, which means it can exert both vertical and horizontal reactions. The vertical reaction can be determined by summing up the vertical forces acting on the beam. The horizontal reaction can be determined by summing up the horizontal forces acting on the beam.

3. Support C: Support C is another roller support, similar to support A. Therefore, it can only exert a vertical reaction. The reaction at support C can be determined by summing up the vertical forces acting on the beam.

The statement "Forging is a deformation process in which the work is compressed between two dies, using either impact or gradual pressure to form the part" is true because the dies exert pressure on the workpiece, causing it to deform.

Forging is indeed a deformation process in which a workpiece is compressed between two dies to shape it into the desired form. Let's take a closer look at how forging works.

In the forging process, the workpiece, often a heated metal billet or ingot, is positioned between two dies. These dies have specific contours and shapes that correspond to the desired final shape of the forged part. The dies are typically made of hardened steel and are usually mounted in a forging press or hammer.

When the forging process begins, compressive forces are applied to the workpiece by closing or striking the dies together. This pressure causes the material to flow and deform, taking the shape defined by the dies. The applied force can be achieved through impact, where a hammer or similar tool strikes the workpiece, or through gradual pressure exerted by a hydraulic or mechanical press.

Complete question:

The acceleration of a particle traveling along a straight line is a = 1/4 s^1/2 m/s^2, where s is in meters. If v = 0, s = 1 m when t = 0, determine the particle’s velocity at s = 2 m.

Answer:

The particle’s velocity is 0.781 m/s.

Explanation:

Given;

acceleration of the particle, \(a = \frac{1}{4} s^{\frac{1}{2}} \ m/s^2\) \(= 0.25s^{0.5} \ m/s^2\)

Acceleration is given by;

\(a = \frac{dv}{dt}\\\\a = \frac{dv}{dt} *\frac{ds}{ds} = \frac{ds}{dt}* \frac{dv}{ds}\\\\a = v*\frac{dv}{ds} \\\\ads = vdv\\\\\int\limits^s_1 {a} \, ds = \int\limits^v_0 {v} \, dv\\\\ \int\limits^s_1 {0.25s^{0.5}} \, ds = \int\limits^v_0 {v} \, dv\\\\\frac{1}{6} (s^{1.5} -1^{1.5}) = \frac{v^2}{2} \\\\v^2 = \frac{2}{6} (s^{1.5} -1^{1.5})\\\\v^2 = \frac{1}{3} (s^{1.5} -1^{1.5})\\\\when \ s= 2 m\\\\v^2 = \frac{1}{3} (2^{1.5} -1^{1.5})\\\\v^2 = 0.6095\\\\v = \sqrt{0.6095}\\\\v = 0.781 \ m/s\)

Therefore, the particle’s velocity at s = 2 m, is 0.781 m/s.

To determine the required size of standard schedule 40 steel pipe to carry 192 m³/hour of water with a minimum velocity of 6.0 m/sec, we can use the following formula:

Q = A × v

where Q is the volumetric flow rate of water, A is the cross-sectional area of the pipe, and v is the velocity of water.

First, we need to convert the volumetric flow rate from m³/hour to m³/sec.

192 m³/hour = 0.0533 m³/sec

Next, we can rearrange the formula to solve for the cross-sectional area:

A = Q / v

A = 0.0533 m³/sec / 6.0 m/sec

A = 0.0089 m²

The cross-sectional area of the pipe is 0.0089 m².

Standard schedule 40 steel pipe has a nominal inside diameter (ID) of 1.049 inches, which is approximately 0.0266 meters. The cross-sectional area of the pipe can be calculated using the formula for the area of a circle:

A = π × (ID/2)²

A = 3.14 × (0.0266/2)²

A = 5.58×10^-4 m²

To determine the required size of the pipe, we can rearrange the formula for the area of a circle to solve for the diameter:

ID = 2 × √(A/π)

ID = 2 × √(0.0089/π)

ID = 0.106 meters

Therefore, the required size of standard schedule 40 steel pipe to carry 192 m³/hour of water with a minimum velocity of 6.0 m/sec is a nominal size of 4 inches, with an inside diameter of 0.102 meters (or 102 millimeters).

capacity q = 165 kPa

depth = 1.5 m

assuming soil unit weight = 17.5 kN

q = 17.5 × 1.5

q = 26.25 kPa

Settlement \(Se = C_1C_2 (\overline q - q) (\dfrac{I_z}{E_s})D_f\)

where;

\(c_1 = 1-0.5 (\dfrac{q}{\overline q -q})\)

\(c_1 = 0.905\)

\(c_2 = 1+ 0.2 log ( \dfrac{t}{0.1})\)

suppose t = 1year

\(c_2 = 1+ 0.2 log ( \dfrac{1}{0.1})\)

\(c_2 = 1.2\)

Using Schertmann method.

\(\mathtt{ I_t = 0.5 }\)

\(\dfrac{length }{breadth } = \dfrac{3}{3}=1\)

∴

E⁵ = \(2.5 q_e\)

E⁵ = 2.5 × 165

E⁵ = 412.5 kPa

Hence: \(Se = C_1C_2 (\overline q - q) (\dfrac{I_z}{E_s})D_f\)

\(Se = 0.905 * 1.2(165-26.25) (\dfrac{0.5}{412.5})*1.5\)
