Français. A power plant is an industrial facility that generates electricity from primary energy. Most power plants use one or more generators that convert mechanical energy into electrical energy [1] in order to supply power to the electrical grid for society's electrical needs. The exception is solar power plants, which use photovoltaic

· The steam tables show that the enthalpy of the turbine inlet steam is 1474.1 Btu per pound of fluid (Btu/lbm). Thermodynamic calculations based on a 10% increase in entropy indicate that the exiting enthalpy from the turbine is 915.0 Btu/lbm (steam quality is 80%). Thus, 1474.1 – 915.0 (= 559.1) Btu/lbm of energy is converted to
