Question

A pump steadily delivers 8.4 kg/s of water at the conditions given below.

Calculate the pump power (kW).

There is no heat transfer from the pump to the surroundings

There are no changes in potential or kinetic energy

Pump inlet temperature: 20 (Celcius)

Pump inlet pressure: 121 kPa

Pump exit temperature: 20 (Celcius)

Pump exit pressure: 563 kPa

So far I have that pump power equals W(dot)=m(dot) (hi - he)

I have many tables provided by my professor but how would I know which one to use to get the enthalpy. I already tried four and none of them give me the answer of -3.72.
