Question 2 (30 marks) (a) A fluid flowing into a nozzle with specific enthalpy of 2980 kJ/kg and the velocity is 80 m/s. At the exit of the nozzle, the specific enthalpy of the fluid drops to 2670 kJ/kg. The nozzle orientation is horizontal and the heat loss is negligible. Given that the nozzle inlet area is 0.25 m2 and the specific volume of the fluid is 0.2 m2/kg, calculate the velocity of the fluid at exit, the mass flow...

thermaldynamics and fluid mechanics
Question 4 An orifice plate flow meter, as shown in figure Q4, is situated in a horizontal pipe of 95 cm diameter (d) in which water flows. The pressure difference between the vena contracta and flow upstream at point 1 is measured using a differential manometer. The diameter of the sharp-edged orifice (d.) is 35 cm. The coefficient of discharge for the flow meter is 0.7, and the coefficient of contraction is 0.62. Assume the density...
