A nozzle is used to increase the velocity of superheated water vapor (steam) which at the nozzle entrance is so low (compared to the velocity at the exit) as to be essentially negligible. In other words, ((v2)^2 - (v1)^2)/2 = (v2)^2/2. The incoming stream has a temperature and pressure of 150 degrees Celsius and 200 kPa. It exits the nozzle as a saturated vapor with a pressure of 75 kPa. Unlike in most nozzles where heat losses are negligible, 26 kJ/kg are lost from the steam as it passes through the nozzle. Calculate (a) the exit velocity of the steam, and (b) the mass fow rate of the steam if the nozzle exit area is 0.001 m^2.
