Question:

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 heat transfer to the working fluid per unit mass (qin) passing through the boiler in kJ/kg.
(b) The thermal efficiency (ηth),
(c) The back-work ratio,
