In an adiabatic nozzle the specific flow energy j remains constant along the flow. The mass flow

Question:

In an adiabatic nozzle the specific flow energy j remains constant along the flow. The mass flow rate through the nozzle is 0.075 kg/s and the following properties are known at the inlet and exit ports. Inlet: p = 200 kPa, u = 2820 kJ/kg, A = 100 cm2, V = 10 m/s; Exit: h = 3013 kJ/kg, v = 1.67 m3/kg. Determine
(a) The exit velocity.
(b) The exit area.
