Problem 3 Steam flows steadily into a turbine with a mass flow rate of 30 kg/s and a negligible velocity at 10 MPa and 700°C. The steam leaves the turbine at 0.8 MPa and 250°C with a velocity of 210 m/s. The rate of work done by the steam in the turbine is measured to be 26 MW. If the elevation change between the turbine inlet and exit is negligible, determine the rate of heat transfer associated with this process. m = 30 kg/s V₁~0m/s P₁ = 10 MPa T₁-700°C Qout Steam turbine V₂-210 m/s P=0.8 MPa T₂=250°C Wout -26 MW
