According to test data, a new type of engine takes in streams of water at 200 ∘∘ C, 3 bar and 100 ∘∘ C, 3 bar. The inlet ratio of the mass flow rate of the higher temperature stream to a lower temperature stream is 0.5. A single stream exits at 3.0 bar with a mass flow rate of 5400 kg/h. There is no significant heat transfer between the engine and its surroundings, and kinetic and potential energy effects are negligible. For operation at steady state, determine the maximum theoretical rate that power can be developed, in kW.
