Low-velocity steam (with negligible kinetic energy) enters an adiabatic nozzle at 300 C and 3 MPa. the steam leaves the nozzle at 2 MPa with a velocity of 400 m/s. the mass flow rate is 0.4 kg/s. determine the quality or temperature (C) of the steam leaving the nozzle and the exit area of the nozzle in mm^2.
