Steam enters a nozzle at 30 bars and 320C and leaves at 15 bars with a velocity of 535 m/s. The mass flow rate is 8000 kg/h. Neglecting the inlet velocity and considering adiabatic flow, compute:
a) the exit enthalpy in kJ/kg
b) the exit temperature in degrees Celsius
c) the nozzle exit are in square centimeters
