Answer:

Explanation:

Temperature of atmospheric air To = 25°C = 298 K

Free  stream velocity of air Vo = 25 m/s

Length and width of plate = 1m

Temperature of plate Tp = 125°C = 398 K

We know for air, Prandtl number Pr = 1

And for air, thermal conductivity K = 24.1×10?³ W/mK

Here, charectorestic dimension D = 1m

Given value of Reynolds number Re = 105

For laminar boundary layer flow over flat plate

= 3.402

Therefore, hx = 0.08199 W/m²K

So, heat transfer rate q = hx×A×(Tp – To)

                                          = 0.08199×1×(398 – 298)

Explanation:

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).

The heat transfer through the concrete wall, separating the conditioned room air from the ambient air, is approximately 1666.67 watts.

The thermal conductivity of a material determines how well it can conduct heat. In this case, the concrete wall has a thermal conductivity of 1 W/m⋅K.
To calculate the heat transfer through the wall, we can use the formula:
Q = (k × A × ΔT) / d
Where:
Q is the heat transfer (in watts)
k is the thermal conductivity (1 W/m⋅K)
A is the surface area of the wall (20 m2)
ΔT is the temperature difference between the inner surface and ambient air (25°C - ambient air temperature)
d is the thickness of the wall (0.30 m)
Let's assume the ambient air temperature is 20°C. So, the temperature difference would be 25°C - 20°C = 5°C.
Substituting the values into the formula, we get:
Q = (1 W/m⋅K × 20 m2 × 5°C) / 0.30 m
Simplifying the equation:
Q = (100 W⋅K × 5°C) / 0.30 m
Q = 500 W⋅K / 0.30 m
Q ≈ 1666.67 W
Therefore, the heat transfer through the concrete wall is approximately 1666.67 watts.

Sucrose purified from sugar cane and sugar beets may have slight variations in impurities and minor chemical composition, but they are nutritionally and chemically identical.

The composition of sucrose purified from sugar cane and sugar beets can differ in terms of impurities and minor chemical variations.

Step 1: Sucrose Extraction

Sucrose is the main component of both sugar cane and sugar beets. The extraction process involves obtaining the juice or sap from the plant source.

Sugar Cane: Sugar cane stalks are crushed to extract the juice, which contains sucrose, water, and other soluble compounds.

Sugar Beets: Sugar beets are washed, sliced, and soaked to extract the sugar-containing juice, which also contains impurities and water.

Step 2: Purification Process

The purification process aims to separate the sucrose from impurities and other components present in the extracted juice.

Sugar Cane: The juice from sugar cane undergoes several purification steps, including clarification, filtration, and carbonation, to remove impurities such as proteins, minerals, and non-sugar compounds. Lime or carbon dioxide is often used to aid in the purification process.

Sugar Beets: The juice extracted from sugar beets goes through a similar purification process, which involves treatments like clarification, filtration, and ion exchange to remove impurities like proteins, pigments, and organic acids.

Step 3: Crystallization and Drying

After purification, the sucrose is concentrated by evaporating the water, leading to the formation of sugar crystals.

Sugar Cane: The concentrated cane syrup is seeded with sugar crystals, and through controlled cooling and stirring, the sucrose crystallizes. The resulting sugar crystals are then separated from the remaining liquid.

Sugar Beets: The concentrated beet syrup is similarly seeded to initiate crystallization. The crystallized sucrose is separated from the syrup using centrifugation or other separation techniques.

Step 4: Final Processing

The separated sugar crystals are further dried to remove any remaining moisture, resulting in the final purified sucrose product.

While the purification processes for sucrose from sugar cane and sugar beets share similarities, there may be slight variations in the specific techniques and chemicals used. These differences can affect the composition of the purified sucrose, including the presence of residual impurities and minor variations in chemical composition. However, from a nutritional standpoint, the sucrose obtained from both sources is chemically identical and provides the same caloric value.

A load of 40 - j 30 is connected to a source of 100 V with a phase angle of 30°. The total power delivered to the load is 184 VA.

The impedance of the load is 40 + j 30 ohms.

The complex power delivered to the load is 100 * (40 + j 30) = 184 + j 78.5 VA.

The real power is 184 * cos(30°) = 160 W.

The reactive power is 184 * sin(30°) = 120 VAR.

The power factor is 160 / (160 + 120) = 0.8.

The total power is the magnitude of the complex power delivered to the load. In this case, the complex power is 184 + j 78.5 VA, so the total power is:

S = \(\sqrt(184^2 + 78.5^2) = 184 VA\)

The total power can also be calculated by adding the real power and reactive power:
