Two components of a steam engine are shown in the figure below. The turbine is adiabatic. 2 boiler turbine m5 kg/s P 8.0 MPa 1-0 T2 300°C 2.5 m3/kg -0.06 MPa The properties of saturated water are giv...
Steam with the mass flow rate of 0.75 kg/s enters an adiabatic turbine steadily at 19 MPa, 600°C and 150 m/s, and leaves at 150 kPa and 350 m/s. The isentropic efficiency of the turbine is 85%. Neglect potential energy. (I) Determine the exit temperature of the steam, and its quality (if saturated mixture) (ii) Calculate the actual power output of the turbine, in kW (iii) Illustrate a T-s diagram with respect to saturation lines for the isentropic process by clearly indicating all pressure, temperature,...
