If the waverider of the Problem 7.44 has the wall temperature of \(1400 \mathrm{~K}\) and \(\operatorname{Re}=1.371 \times 10^{6}\) with respect to its length then find the drag coefficient with reference temperature method. Use this result to determine (L/D) with total drag.

Problem 7.44

Find for a waverider flying at \(80 \mathrm{~km}\) altitude with a Mach number of 25, find:

(i) approximate lifting pressure, 

(ii) lift coefficient, and induced drag coefficient. Assume ideal flow.
