Answer to Question #131382 in Mechanical Engineering for syahmi asyraaf

Question

Air at 6.9 bars 260oC is throttled to 5.5bars before expanding through a nozzle to a pressure of 1.1 bars. Assuming that the air flows reversibly in steady flow through the nozzle, and that no heat is rejected. Calculate the velocity of the air at exit from the nozzle when the inlet velocity is 100 m/s.

Assume for perfect gas h = cpT and for throttling process T1 = T2
