A Rankine heat engine is to be designed, with the following specifications and constraints:

• The boiler will operate at a maximum T = 200°C.
• The condenser will operate at a minimum T = 100°C.
• The turbine has an efficiency of 75%.
• The liquid fraction exiting the turbine cannot exceed 10%.
• Water, in liquid and/or vapor form, is the operating fluid Determine the state of the water entering each of the four steps of the process in Figure 5-6, the efficiency of the heat engine, and the mass flow rate of water necessary for the engine to produce 10 MW of net work.
