The basic operation of the steam turbine is similar to the gas turbine except that the working fluid is water and steam (with a phase change) . T_out = theoretical temperature of the steam exiting the cylinder after expansion, assuming perfect adiabatic expansion and no condensation. The density of water vapor at 100 C at atmospheric pressure is about a factor of 1600 less, and so water expands by a factor of 1600 when it turns into steam at atmospheric pressure. 1 What is the expansion rate of water to steam? Heat is then added and the fluid expands at constant pressure until it reaches a saturated vapor state. By condensing the working steam to a liquid (inside a condenser) the pressure at the turbine outlet is lowered and the energy required by the feed pump consumes only 1% to 3% of the turbine output power and these factors contribute to a higher efficiency for the cycle.
