If the air is flowing at a static temperature of 273 K and Mach 4, what is its quiescent temperature, and if the above air flow passes through a flat plate, in real conditions a boundary layer is formed on the flat plate. Given that the absolute velocity of the current on the flat surface is zero, can the stagnation temperature be expected to reach free flow?
