A simple ideal Rankine cycle with water as the working fluid operates between the pressure limits of 17.5 MPa in the boiler and 30 kPa in the condenser. What is the minimum temperature required at the turbine inlet such that the quality of the steam leaving the turbine is not below 80%? When operated at this temperature, what is the thermal efficiency of this cycle?
