20 kmol/hr of liquid water is pumped isothermally from 1 atm to 50 atm, the water is heated isobarically until it boils and becomes superheated steam, it is passed through a turbine where the pressure drops to 1 atm, then it passes through a compressor which raises the pressure to 5 atm. a) Assume that the compressor operates isothermally, and the inlet temperature is 600 K. What is the work of the compressor in kW? b) The enthalpy change across the compressor is 20 kJ/mol. How much heat is released by the compressor in kW? c) The compressor is cooled with cooling water. If the heat capacity of the cooling water is 4.2 J/mol°C, the inlet temperature is 25°C, and the outlet temperature cannot be greater than 40°C, what is the flow rate of the cooling water in kmol/hr?
