Air enters a nozzle with a diameter of 4 cm at 10 m/s, P1 = 400 kPa, and T1 = 60ºC. It exits at a diameter of 2 cm at atmospheric pressure. The maximum possible exiting velocity is nearest:

A) 470 m/s
B) 410 m/s
C) 320 m/s
D) 260 m/s


A) 470 m/s

The air flow is approximated as an adiabatic quasi-equilibrium flow which provides the maximum

possible exiting velocity (no heat loss, no friction, and no shock waves). The exiting temperature

would be
