8.2 Irreversible Turbine A mass flow of 200 t/hr steam passes through a well-insulated (i.e., adiabatic) turbine operating at steady state. The steam enters at 550C, 90 bar, and exits as saturated liquid-vapor mix with quality of 0.9 at 40 C. The inlet velocity is 40m/s, and the outlet velocity is 80m/s. a) Determine the power generation of the turbine. Show that kinetic energy can be ignored. b) Determine the isentropic efficiency of the turbine c) Determine entropy generation and corresponding lost work (use To)
