Example A steam turbine receives steam with a specific enthalpy of 3121 kJ/kg. The steam leaves the turbine with a specific enthalpy of 2676 kJ/kg. The steam enters and leaves the turbine with velocities of 15 m/s and 60m/s. The elevation difference between the entry and exit ports is negligible and the heat energy lost through the turbine walls is 7600 kJ/h. Calculate the power output if the mass flow through the turbine is 0.5 kg/s. High pressure steam Low...

A steam power plant design consists of an ideal Rankine cycle with regeneration. Steam enters Turbine 1 at P1 and T1 at the rate of m1 and exits at P2. A fraction (y') of the steam exiting Turbine 1 is diverted to a closed feedwater heater while the remainder enters Turbine 2. A portion (y'') of the steam exiting Turbine 2 at P3 is diverted to an open feedwater heater while the remainder enters Turbine 3. The exit of Turbine...
