# enthalpy of fluid passing is 2800 kJ/kg…. solved problem

#### At the inlet to a certain nozzle the enthalpy of fluid passing is 2800 kJ/kg, and the velocity is 50 m/s. At the discharge end the enthalpy is 2600 kJ/kg. The nozzle is horizontal and there is negligible heat loss from it. (i) Find the velocity at exit of the nozzle. (ii) If the inlet area is 900 cm2 and the specific volume at inlet is 0.187 m3/kg, find the mass flow rate. (iii) If the specific volume at the nozzle exit is 0.498 m3/kg, find the exit area of nozzle.
