Pressure: 3 MPa
Temperature: 400°C
Condenser exit
Pressure: 15 kPa
Mass flow rate: 1.9 kg/s
Boiler
Pump
Turbine
Condenser
(a) Sketch the cycle on a T-s diagram with respect to saturation lines, label the exit of the
condenser as point 1 and indicate the two indicated pressure values at the proper locations
of the cycle.
(b) Determine the specific enthalpy of the working fluid at the pump exit.
(c) Determine the power of the turbine.
