Consider a steady-flow Carnot cycle with water as the working fluid executed under the saturation dome between the pressure limits of 8 MPa and 20 kPa. Water changes from saturated liquid to saturated vapor during the heat addition process. The net work output of this cycle is
(a) 494 kJ/kg
(b) 975 kJ/kg
(c) 596 kJ/kg
(d) 845 kJ/kg
(e) 1148 kJ/kg
