The pump of Fig. 6.60 is used in a power plant to increase the low pressure of saturated liquid water exiting a condenser to a high pressure entering a boiler. Estimate the efficiency of the pump if it accepts 2400 kg of water each minute at 10 kPa and discharges it at 8 MPa while consuming 4000 kWh of energy over a 10-hour period.
