Question

Saturated steam at a gauge pressure of 3.00 bar is to be used to heat a stream of ethane. The ethane enters a heat exchanger at 16°C and 253 bar gauge pressure at a rate of 695m²/m*in and is heated at constant pressure to 93°C. The steam condenses and leaves the exchanger as a liquid at 240°C. The specific enthalpy of ethane at the given pressure is 941 kJ/h·g at 16°C and 1073 kJ/l·g at 93°C. You may take the compressibility factor for ethane to be 0.970 at the inlet conditions.

Answer 1

To estimate the temperature at which 1.00 kg of steam at a pressure of 1.50 × 10^6 Pa occupies a volume of 0.220 m³, we can use the ideal gas equation.

Step-by-step explanation:

The subject of this question is Physics, and it is a College-level question.

To estimate the temperature at which 1.00 kg of steam at a pressure of 1.50 × 10^6 Pa occupies a volume of 0.220 m³, we can use the ideal gas equation. The equation is:

PV = nRT

where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature. Rearranging the equation to solve for T, we have:

T = PV / (nR)

By substituting the given values, we can calculate the temperature.
