Saturated liquid water at 25 degrees C is pumped to a pressure of 5 MPa in an isothermal process. The specific work required by the pump to pressurize the water to 5 MPa can be found as the change in enthalpy of the water from the inlet pressure to the outlet pressure (5 MPa). Find the following:
1) What is the work required using the saturated liquid approximation?
2) What is the work required using the compressed liquid tables?
3) What is the work required if you use the mechanical energy equation?
