A steam turbine produces 1000 hp at its shaft output. Superheated steam enters the turbine through a 3-inch ID pipe at a temperature T1 = 1200°F, a pressure of P1 = 380 psia, a specific enthalpy of hi = 1631.6 Btu/lbm, and a velocity of vị = 100 ft/s. The superheated steam leaves the turbine at a specific enthalpy of h2 = 1238.1 Btu/lbm and a velocity of v2 discharge line is 10 ft below the entrance line. Assume that the turbine operates adiabatically and steam behaves as an ideal gas. Determine the power lost to friction in the bearings of the turbine. 300 ft/s. The

Question
Transcribed Image Text:A steam turbine produces 1000 hp at its shaft output. Superheated steam enters the turbine
through a 3-inch ID pipe at a temperature T1 = 1200°F, a pressure of P1 = 380 psia, a specific
enthalpy of hi = 1631.6 Btu/lbm, and a velocity of vị = 100 ft/s. The superheated steam leaves
the turbine at a specific enthalpy of h2 = 1238.1 Btu/lbm and a velocity of v2
discharge line is 10 ft below the entrance line. Assume that the turbine operates adiabatically
and steam behaves as an ideal gas. Determine the power lost to friction in the bearings of the
turbine.
