The temperature is 320 K, screw 20 bar, and the value shown in real gas industrial production is 380 and 100 bar. The compression process transfers 150 kJ/kg of heat.

Calculate the work (kJ/kg) and work (kJ/kg) for these processes using the van der Waals equation of state. The environment is 293K, it has information about them. Cpig H= 49.24 kJ/kmolK Cpig S= 49.16 kJ/kmolK
