Air enters an isentropic turbine at 16 atm and 1500 k and is expanded to 5 atm. heat is then added at constant pressure to the air until the temperature rises to 1200 k. the heated air finally enters an isentropic nozzle and expands to 1 atm. illustrate the process on p ? v and t ? s diagrams. a) determine the temperature at the exit of the turbine. b) how much specific power is produced by the turbine? c) between the turbine and the nozzle, what is the rate of heat addition per kg? what is the rate of entropy generation associated with this heat transfer? d) by neglecting the velocity at the inlet of the nozzle, determine the jet velocity at the exit. e) if the nozzle is adiabatic (but not isentropic), with an isentropic efficiency of 90%,what is the exit velocity in this case? what is the associated rate of entropy change? represent the process on a t ? s diagram, indicating the heat added between the turbine and the nozzle.
