A normal shock is positioned in the diverging portion of a frictionless, adiabatic, converging-diverging air flow duct where the cross-section area is 0.1 ft2 and the Mach number is 2.0. Upstream of the shock, po2 = 200 psia and To = 1200 oR. If the duct exit area is 0.15 ft2, determine the exit area temperature and pressure and the duct mass flow rate.
