Compressed air is discharged through a converging nozzle as shown in the accompanying figure. The conditions in the tank are 1 MPa and 500 K while the outside pressure is 100 kPa. The inlet area of the nozzle is 100 cm2 and the exit area is 35 cm2. Determine
(a) The exit temperature and
(b) The exit velocity,
(c) The force of the air on the nozzle. Assume the conditions inside to remain unchanged during the discharge.
