A 110-scale model of an airplane is tested in a wind tunnel at70F and 14.40 psia. The model test results are:Velocity (mph) 0 50 100 150 200Drag (lb) 0 5 21 46 85.Find the corresponding airplane velocities and drags if only fluidcompressibility is important and the airplane is flying in the U.S.Standard Atmosphere at 30,000 ft. Assume that the air is an ideal gas.
