Steam enters a turbine at a pressure of 6.0 MPa and temperature of 460 °C. Steam exits the turbine at a pressure of 150 kPa and quality of 0.91. Steam velocity at the entrance is 100 m/s and at exit is 15 m/s. If the heat loss and mechanical loss are negligible, find: a) The output work of turbine (work of shaft) per unit mass of flow. b) The required mass flow rate for a 5.0 MW output power of shaft. P₁ = 6.0 Ma T₁ = 460 °C V₁ = 100 m/s Steam m=12 kg/s P. = 150 kPa Xo = 0.91 V, 15 m/s W out Steam enters a turbine at a pressure of 6.0 MPa and temperature of 460 °C.
