Saturated liquid water is compressed from 100 kpa state 1

Assignment Help Mechanical Engineering

Saturated liquid water is compressed from 100 kPa (State 1) to 2.5 MPa (State 2) in an adiabatic pump having 85% isentropic efficiency.

(a) Calculate the specific work (kJ/kg) required for the compression of liquid water.

(b) Determine the entropy generation (kJ/kg-K) for the pump.
