A simple 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 vapor enters a turbine. Irreversibilities in the turbine cause the turbine to be 70 percent. Determine isentropic efficiency of the turbine and thermal efficiency of the cycle
