[3] (25%) Water is the working fluid in a Carnot vapor power cycle. Saturated liquid enters the boiler at a pressure of 10 MPa, and saturated vapor enters the turbine. The condenser pressure is 10kPa. Determine: (a) the thermal efficiency (b) the back work ratio (c) the heat transfer to the working fluid per unit mass passing through the boiler, in kJ/kg (d) the heat transfer from the working fluid per unit mass passing through the condenser, in kJ/kg.
