Question 5 Methane flows at a rate of 2.5 kg/s in a converging-diverging nozzle of circular cross-section. The flow throughout the nozzle is isentropic, one-dimensional and steady. The stagnation pressure is 640 kPa and the stagnation temperature is 380 K. Methane is assumed to be a perfect gas with specific heat ratio k = 1.32 and constant R = 518 J/kg.K. If the exit pressure is atmospheric (101325 Pa), determine the following quantities: (a) (b) (c) Exit velocity Throat area Exit Mach number (6 Marks) (2 Marks) (2 Marks) (Total: 10 Marks) Question 5 Methane flows at a rate of 2.5 kg/s in a converging-diverging nozzle of circular cross-section.
