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 a saturated vapor. The condenser pressure is 9 kPa. Determine 

(a)the diagram; 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 90 kPa
