Question

Physics: Air enters a nozzle steadily at 280 kPa and 77 oC 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 oC are estimated to be 3.2 kJ/kg. Determine (a) the exit temperature and (b) the total entropy change for this process
