Question
Water vapor enters a compressor at a pressure of 100 kPa, a temperature of 100°C and a mass flow of 1.1 kg/s, and exits at a pressure of 500 kPa and a temperature of 500°C.Heat transfer from the surface of the compressor to the environment is 75 kW and the limit temperature between the compressor and the environment is 100°C.,
a) find the Exergy of the fluid at the inlet of the compressor (kW).
b) find the Exergy of the fluid at the output of the compressor (kW).
c) find the Second Law efficiency of the compressor.
d) find the Exergy (Exergy extinction) that has disappeared (kW).
Note: changes in kinetic and potential energies will be neglected and
T (k) = 273 + °C will be. The pressure of the environment is 100 kPa and the temperature is 25°C.
