Expand given Problem by replacing the ideal gas properties with a gas menu that contains a computerized version of the isentropic gas tables as the source of the enthalpy values.

Problem :

Develop an interactive reversed Brayton ASC computer program that utilizes constant specific heat ideal gas equations of state as the source of the enthalpy values. Allow the user to select either a refrigeration, air conditioning, or heat pump application.

Have the user input the appropriate gas constants (or choose the gas from a screen menu), the source and sink temperatures, the mass flow rate of the gas, and the isentropic pressure ratio, PR.

Output the coefficient of performance, the source and sink heat transfer rates, and the net power input. Use this program to plot the coefficient of performance vs. the PR for a reversed Brayton cycle refrigerator operating between 20.0°C and -14.0°C.

Allow the PR to range from 1.00 to 14.0.
