Question
A pump brings in 20.0 kg/s of liquid water feed at 1.92 bar and 50 °C. The exit pressure from this
pump is 7.05 bar. The pump (being real, not reversible) has an isentropic efficiency of 82%. What is
the actual work input (in kW) required to run this pump, assuming the specific volume of the water
remains constant at 0.001012 m³/kg?
