Steam flows steadily through a turbine at a rate of 45,000 lbm/hr, entering at 1,000 lbf/in2 and 900oF and leaving at a pressure of 5 lbf/in2. If the power generated by the turbine is 1.37x107 Btu/hr and the turbine is cooled at a rate of 7x106 Btu/hr, determine the temperature of the steam at the exit [oF]. Show the inlet and exit states on a P-v diagram.

A ship's steam turbine receives 7200 lbm/min of steam at pressure of 900psia and a velocity of 100ft/s. The steam leaves the turbine at 450 psia with a velocity of 800 ft/s. Specific enthalpy at the inlet and exit, respectively, are 1508.9 Btu/lbm and 1238.5 Btu/lbm. As the steam passes through turbine 12 Btu/lbm of heat is lost to the environment. a) Using the Steady Flow Energy Equation, determine the specific work generated by this turbine. (Btu/lbm) b) Determine the...
