Steam enters a nozzle with a low velocity at 300*F and 30 PSI, and leaves as saturated vapor at 10 PSI. There is heat loss from the nozzle in the amount of 25 BTU/lbm. Determine the exit velocity of the stream (ft/s) and the mass flow rate (lbm/s) of the steam at the nozzle entrance if the nozzle exit area is 0.01ft^2.
