Unformatted text preview: Engineering units (SI) for pressures & Pe Pi is , Pascal Pa for specific volumes, & ve vi is / m3 kg ** Subscripts e for exit and i for inlet. And, is the specific heat ratio which is a constant for ideal gas given by = CpoCv0 From the thermodynamic property table for ideal gas, we can directly obtain the values of Cpo and Cvo for Propane. Then, CpoCvo will give us value of Engineering units (SI) for specific heat at constant pressure, Cpo is kJkgK specific heat at constant volume, Cvo is kJkgK specific enthalpy at exit, he is / kJ kg specific enthalpy at inlet, hi is / kJ kg Using equation [1] we can obtain the polytropic efficiency for this case....
