Information
Example of a steam power plant.
English problem description
Saturated liquid water (32.90 degC, 50.0 mbar, 84.316 kg/s)
is pumped in a reversible adiabatic feedwater pump to 20.0 bar.
In the isobaric heater, the water is heated, vaporized and superheated (288 MW).
The heater is adiabatic on the outside.
The steam is then expanded in the steam turbine (isentropic efficiency
eta_is = 0.889), condensed in the isobaric condenser and returned to the pump, closing the cycle.
