Consider a steady air flow from a reservoir through a converging-diverging nozzle. Reservoir pressure and temperature are p. = 20 bar and To = 310 K respectively. In the diverging part of the nozzle a shock has formed at a location where the cross sectional area is A=7.0x104 m². The Mach number downstream of the shock is M2=0.55. Air can be considered an ideal gas with R/m=287 J/(kg:K) and y=1.4. a. Determine the Mach number directly upstream of the shock. [4 marks) b. Determine the mass flux through the nozzle. [12 marks] c. Determine the change in entropy over the shock. [4 marks]
