In an experimental set-up, air flows between two stations P and Q adiabatically. The direction of flow depends on the pressure and temperature conditions maintained at P and Q. The conditions at station P are 150 kPa and 350 K. The temperature at station Q is 300 K.
The following are the properties and relations pertaining to air:
Specific heat at constant pressure, CP =1.005 kJ/kgK;
Specific heat at constant volume, CV = 0.718 kJ/kgK;
Characteristic gas constant, R = 0.287 kJ/kgK
Enthalpy, h = CpT
Internal energy, u = CVT
