take a look back at Equation 8.80, which is the ratio of Pitot pressure to freestream static pressure in a supersonic flow. This Equation DOES NOT hold for an oblique shock wave. In as such, the p0,2/p1 Column in Appendix B CANNOT be used, in conjunction with the upstream Mach number, to obtain the total pressure behind an oblique shock wave. However, the p0,2/p0,1 Column can be used for an oblique shock wave, using Mn,1. Discuss why this is true
