Problem 6.27:

A Rankine steam power plant produces 0.5 MW of mechanical power by expanding steam from 60 bar, 700 °C, to 3 bar. The efficiency of the turbine and of the pump is 80%. Calculate the energy balances, determine the flow rate of steam, and determine the entropy generation in each unit.

Problem 6.28:

The boiler of a Rankine power cycle absorbs 1000 kW of heat from a furnace at 700 °C. The power plant rejects 850 kW of heat in a river at 25 °C.

a) What is the efficiency of the cycle?

b) What is the rate of entropy generation?

c) What is the maximum possible power that could be produced by a plant given the temperatures of the furnace and the river?
