An airplane is cruising at a velocity of 800 km/h in air whose density is 0.526 kg/m

Question:

An airplane is cruising at a velocity of 800 km/h in air whose density is 0.526 kg/m³. The airplane has a wing planform area of 90 m². The lift and drag coefficients on cruising conditions are estimated to be 2.0 and 0.06, respectively. The power that needs to be supplied to provide enough trust to overcome wing drag is

(a) 9760 kW

(b) 11,300 kW
