Rankine Cycle
Rankine cycle is a heat engine with vapor power cycle. The common working fluid is water.
The cycle consists of four processes:
1 to 2: Isentropic expansion (Steam turbine)
2 to 3: Isobaric heat rejection (Condenser)
3 to 4: Isentropic compression (Pump)
4 to 1: Isobaric heat supply (Boiler)
Work output of the cycle (Steam turbine), W1 and work input to the cycle (Pump), W2 are:
W1 = m (h1-h2)
W2 = m (h4-h3)
where m is the mass flow of the cycle. Heat supplied to the cycle (boiler), Q1 and heat
rejected from the cycle (condenser), Q2 are:
Q1 = m (h1-h4)
Q2 = m (h2-h3)
The net work output of the cycle is:
W = W1 - W2
The thermal efficiency of a Rankine cycle is:
