Ethylene at the temprature and pressure of 320K and 20 bar enters a compressor and leaves it at 380K and 100 bar. During the compression process, 150kj/kg of heat is transferred from the sytem to the environment. Ethylene acts like a real gas. Using the Van der Waals equation of state, calculate the actual work(kj/kg) and the work lost during the process (kj/kg). The environment's temprature is 293K. Potential and Kynetic energies are negligable. ( Cp ig H= 49.24 kJ/kmolK Cp ig S= 49.16 kJ/kmolK )
