Steam enters a nozzle operating at steady state with p = 40 bar and T =400oC, and a velocity of 10 m/s. The steam flows through the nozzle with negligible heat transfer and no significant change in potential energy. At the exit, p2 = 15 bar and the velocity is 605 m/s. The mass flow rate is 2 kg/s. Determine the exit area of the nozzle.
