Determine the area and velocity at the exit of the convergent nozzle through which it flows an isentropic gas (k = 1,4; R = 287Nm/kg.K). What is the lowest possible value for the outlet of the nozzle while maintaining isoentropic flow? (For the same input conditions). Data: Pressure1 = 207 kPa ; Density1 = 1,3 kg/m³ ; Velocity1 = 47,2 m/s ; Area1 = 0,1m² . Pressure2 = 172,5 kPa

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...
