Question

The jet plane is flying upward such that its wings make an angle of attack of 20∘ with the horizontal. The plane is traveling at 850m/s, in air having a temperature of −4∘C and absolute pressure of 40 kPakPa. The leading edge of the wing has an angle of 24∘. For air, k = 1.4 and R = 286.9 J/[kg⋅K]J/[kg⋅K]. (Figure 1). 
A. Determine the pressure of the air just in front or to the right of the expansion waves.
B. Determine the temperature of the air just in front or to the right of the expansion waves.
