Problem 3- [4 points] Air is flowing at a Mach number of 2 and a pressure of 70 kPa in a two-dimensional channel. The

Problem 3- [4 points] Air is flowing at a Mach number of 2 and a pressure of 70 kPa in a two-dimensional channel. The upper wall turns towards the flow through an angle of 5 and the lower wall turns towards the flow through an angle of 3, two oblique shock waves thus being generated. These two shock waves intersect each other. 1. Make a sketch of the situation. 2. Find the pressure in the region just downstream of the shock intersection (iterations may be needed). constant specific heat y Unless specified otherwise, assume the working fluid is air and it can be treated as an ideal gas with 1.4. The specific gas constant for air is R = 287 J/kg.K in SI units or R = 1716 ft.lb/slug.R in English units. =
