Water is then pumped into the boiler upto the pressure corresponding to the state 1 and the cycle is completed. Such a cycle is known as the Rankine cycle. This theoretical cycle is free of all the practical limitations of the Carnot cycle.

Figure 2(b) shows the schematic diagram for a simple steam power cycle which works on the principle of a Rankine cycle. The Rankine cycle comprises the following processes.

Process 1-2: Constant pressure heat transfer process in the boiler Process 2-3: Reversible adiabatic expansion process in the steam turbine Process 3-4: Constant pressure heat transfer process in the condenser and Process 4-1: Reversible adiabatic compression process in the pump.
