The Rankine Cycle

The condenser effluent in a

Rankine Cycle

is a saturated liquid.

Rankine Cycle

Process 1-2:
Process 2-3:
Process 3-4:
Process 4-1:
  • Heat added at constant pressure.
  • Isentropic expansion
  • Heat rejected at constant pressure.
  • Isentropic compression

Rankine Cycle

is the practical

vapor power cycle

that is most similar to a

Carnot Cycle

The boiler effluent is either saturated vapor or superheated vapor.
