Question Numbers: 58-59 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, C_P =1.005 kJ/kgK;Specific heat at constant volume, C_V = 0.718 kJ/kgK;Characteristic gas constant, R = 0.287 kJ/kgKEnthalpy, h = C_pTInternal energy, u = C_VT
