Moist air at 35 degree C, 3 bar, and relative humidity 30% (State 1) enters a nozzle with a velocity of 50 m/s and expands in a reversible and adiabatic process such that the moist air leaving the nozzle is about to condense (State 2).
a) Calculate the pressure (bar) at the nozzle exit.
b) Determine the velocity (m/s) at the nozzle exit.
