The following diagram illustrates a simple steam power plant. A
10kg/s flow of liquid water at T1=25°C enters the pump at a
pressure of P1=100kPa and is then pumped to a pressure of P2=2MPa.
The boiler then heats the water at constant pressure to produce
superheated vapour at T3=450°C. The steam is then expanded in the
turbine to a final pressure of P4=100kPa. The turbine and pump are
well insulated and may be considered reversible.
