Air enters an isothermal nozzle at a temperature of 300 K, and a velocity of 10 m/s. The nozzle is very poorly insulated, causing a stray heat transfer rate of 10 kW into the system. The outlet of the nozzle is exposed to an ambient pressure of 1 bar and is choked (Mach = 1). If the area ratio of the nozzle (A, /A2) is 5, what is: The velocity of the nozzle outlet, in [m/s], if the specific heat...
