Asteam power plant operates on a simple ideal rankine cycle between the pressure limits of 3 mpa and 50 kpa. the temperature of the steam at the turbine inlet is 300°c, and the mass flow rate of steam through the cycle is 34 kg/s. determine the thermal efficiency of the cycle. determine the net work output of the rankin cycle in mw

Air (c-1.006 kj/kg.k, r-0.287 kj/kg.k) enters a nozzle steadily at 280 kpa and 77°c with a velocity of 50 m/s and exits at 85 kpa and 320 m/s. the heat losses from the nozzle to the surrounding medium at 20°c are estimated to be 3.2 kj/kg. determine (a) the exit temperature and (b) the total entropy change for this process. solve this problem using constant specific heats.
