Q2: 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 3025 kJ/kg, the inlet area is 0.1 m and the specific volume is 0.19m'/kg. At the exit from the nozzle the specific enthalpy is 2790 kJ/kg, the area is 0.023 m and the specific volume is 0.5 m /kg. The nozzle is horizontal and there is a negligible heat loss from it. Calculate: i) The velocity of the fluid at the inlet and exist; ii) The rate of flow of fluid
