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...
Question 3 (40 marks) (a) Air enters a horizontal nozzle with a velocity of 1 m/s, a pressure of 2 bar and a temperature of 350 K. At exit from nozzle, the air temperature is 450 K. The combined rate of specific heat transfers, and specific work transfers, w to the air as it passes through the nozzle is 150 kJ/kg. Assume that the air flow is steady and air can be treated as perfect gas with = 1005 J/(kg.K)....

3. (15 marks) As shown in the figure, a chamber has two pipe inlets (indicated using 1 and 2) and a nozzle outlet (indicated using 3). Helium gas flows through the system, and can be treated as an ideal gas with constant specific heats. The pressure of the helium at the two inlets and outlet is P, = 10 MPa, P2-15 MPa and P3-8 MPa, and the corresponding velocity of the helium gas is V - 10 m/s, V,- 15...
