Calculate the ratio of the drag force on a passenger jet flying with a speed of 1200 km/h at an altitude of 10 km to the drag force on a prop-driven transport flying at one-fourth the speed and half the altitude of the jet. At 10 km the density of air is 0.38 kg/m3 and at 5.0 km it is 0.67 kg/m3. Assume that the airplanes have the same effective cross-sectional area and the same drag coefficient C. (drag on jet / drag on transport)
Answers: 1
= Velocity of the passenger jet = 1200 km/h = 
= Velocity of the prop plane = 
= Density of the air where the jet was flying = 
= Density of the air where the prop plane was flying =
