Question

B. 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 and the velocity is 60 m/s. At the exit from the nozzle the specific enthalpy is 2790 kJ/kg. The nozzle is horizontal and there is a negligible heat loss from it. Calculate the following: 1- The velocity of the fluid at exit. 2- The rate of follow of fluid when the inlet area is 0.1 m² and the specific volume at the inlet is 0.19 m³/kg. 3- The exit area of the nozzle when the specific volume at the nozzle exit is 0.5m³/kg. C. If the Joule-Kelvin coefficient ? = V/Cp(?T - 1), where the coefficient of volume expansion ? = 1/V(?V/?T)p. Prove that: ?=0 for perfect gas. [Given: PV = RT]. ]. Good Luck!
