The pump in the Rankine cycle raises the pressure of 12 kg/s of water from 20 kPa to 8 MPa. The boiler raises the temperature to 700°C, and the steam exits the turbine at a quality of 0.9, as sketched in the figure. Assume the pump and turbine are adiabatic.
The minimum power required by the pump is nearest:
A) 9.9 hp
B) 10.7 hp
C) 12.2 hp
D) 13.8 hp
B) 10.7 hp
The minimum power required by the pump is
A pump, like any other device, always has some losses associated with it so the power that
this pump actually required would be larger than 10.7 hp.
