Read MoreIf the amount of heat required for this purpose is supplied internally, the cycle thermal efficiency would approach to that of Carnot cycle. Dry saturated steam at 17.5 bar enters the turbine of a steam power plant and expands to the condenser pressure of 0.75

Read MoreA well-insulated turbine operating at steady state delivers 28.75 MW of power for a steam flow rate of 50 kg/s. The steam enters at 20 bar with a velocity of 61 m/s and exits as saturated water vapor at 0.06 bar with a velocity of 130 m/s. Neglect potential energy
