Air is expanded isentropically a horizontal nozzle from an initial pressure of 1.0 mpa, of a temperature of 800 k, to an exhaust pressure of 101 kpa. if the air enters the nozzle with a velocity of 100 m/s, determine the air exhaust velocity. assume the air behaves as a perfect gas, with r = 0.287 kj/kg . k and y = 1.4. repeat for a vertical nozzle with exhaust plane 2.0 m above the intake plane.
