Question

A simple ideal Rankine cycle with water as the working fluid operates between the pressure limits of 15 MPa in the boiler and 100 kPa in the condenser. Saturated steam enters the turbine. Determine the work produced by the turbine, the heat transferred in the boiler, and thermal efficiency of the cycle. As part of your solution, sketch a simplified diagram of the cycle, labelling each component, indicating where heat and work flows into or out of the system, and the direction of flow of the water. List all your assumptions.
