1. In a typical nozzle, air is used as a medium to undergo increased velocity at the exit. Air at 627 0C enters into a nozzle with negligible velocity and leaves at 27 0C. Determine the velocity of air the exit, assuming no heat loss and nozzle being horizontal. Take the value of Cp = 1.005 kJ/kg K for air. Also, determine the area of the nozzle at the exit, if the density of the air is 1.12 kg/m3.
