A nozzle is a device for increasing the velocity of a steadily flowing fluid. At the inlet to
a certain nozzle the specific enthalpy of the fluid is 3045 kJ/kg and the velocity is 70 m/s.
At the exit from the nozzle specific enthalpy is 2850 kJ/kg. The nozzle is horizontal and
there is a negligible heat loss from it. Determine;
i. The velocity of the fluid at exit
ii. The rate of flow of fluid when the inlet area is 0.1 m2
and the specific volume at
inlet is 0.19 m3
