When compressed air expands from 20.0°C, 100. atm to 1.00 atm, the mean Joule-Thomson coefficient is 0.150°C/atm.
Determine the outlet temperature and the coefficient of performance of an expansion air conditioning system operating under these conditions when the compressor isentropic efficiency is 80.0%.
At 700.°C, the total pressure of the system is found to be 3.63 atm. If the equilibrium constant KP is 1.52, calculate the equilibrium partial pressures of CO2 and CO.
