Determine the thermal efficiency of the power plant

Reference no: EM131348623

Saltwater oceans have subsurface stratification layers called thermoclines across which large temperature differences can exist. A 1.00 MW Rankine cycle power plant using ammonia as the working fluid is being designed to operate on a thermocline temperature difference.

The ammonia exits the boiler as a saturated vapor at 28.0°C and exits the condenser as a saturated liquid at 10.0°C. For an isentropic system, determine

a. The thermal efficiency of the power plant.

b. The pump to turbine power ratio.

c. The required mass flow rate of ammonia.
