1. Find the maximum increase in density across a shock wave for a gas with γ = 1.4.
2. A blowdown wind tunnel is supplied by a large air reservoir where the pressure is constant at 1.014×105 P a and the temperature is constant at 15°C. The air passes through a working section of area 0.04 m2 and exits to a large vacuum vessel. Find the pressure, density, velocity and mass flow rate in the working section if the Mach number there is 4.0.
