Problem Set 13, PS13 due Friday June 18 The power output of an adiabatic turbine is 8 MW. Steam enters the turbine at 600 C, 6 MPa and 80 m/sec. Steam leaves the turbine at 50 kPa, 100 C and 140 m/sec. Determine a) the turbine steam mass flow rate, b) the isentropic efficiency of the turbine. c) the entropy change in the expansion process. PS13-1 6-102 An air compressor has an adiabatic efficiency of 84%. Air enters the compressor at 100 kPa , 17 C and a negligible velocity. Air leaves the compressor at 257 C and a negligible velocity. Determine a) the compressor exit pressure and b) the power input to the compressor. PS13-2 Consider the effect of varying the isentropic efficiency of an adiabatic nozzle from 80% to 100% on the nozzle exit temperature and pressure. Inlet conditions and the exit velocity are held constant. Air enters the nozzle at 60 psia, 1020 F and a low velocity. Air leaves the nozzle at with a velocity of 800 ft.sec. PS13-3
