Mechanical effort Steam

steam engines , steam turbines use expansion of steam drive piston or turbine perform mechanical work. ability return condensed steam water-liquid boiler @ high pressure relatively little expenditure of pumping power important. condensation of steam water occurs @ low-pressure end of steam turbine, since maximizes energy efficiency, such wet-steam conditions must limited avoid excessive turbine blade erosion. engineers use idealised thermodynamic cycle, rankine cycle, model behavior of steam engines. steam turbines used in production of electricity.
