1. Water is the working fluid in a Carnot vapor power cycle. Saturated liquid enters the boiler at a pressure of 10 MPa, and enters the turbine as saturated vapor. The condenser pressure is 9 kPa. 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 and (d) the heat transfer from the working fluid per unit mass passing through the condenser in kJ/kg. (e) What-if Scenario: What would the thermal efficiency be if the steam entered the turbine at 5 MPa and the condenser pressure were 90kPa?
