T_stag = (59F - .00356(F/ft) * h_{max_v} (ft)) + (4.9776008*10^{-4}) * (v_2 * cos(λ))^2
v_2 = Mach 2 = 2*343 (m/s) = 686 (m/s)
T_stag = (59F - .00356(F/ft) * h_{max_v} (ft)) + (4.9776008*10^{-4}) * (686 (m/s) * cos(λ))^2
Note that the first half is in degrees F whereas the second half of the sum will be in degrees K.
Dynamic Pressure
Dynamic pressure (q) represents the aerodynamic pressure exerted on a vehicle in motion through a fluid (air). It is defined by the equation:
