Flow-Past-Through-Submerged-Body

An aircraft weighing 1000 KN when empty has a wing area of 220 `m^2`. It is to take off at a velocity of 300km/hr and a `20^0` angle of attack. Determine allowable weight of cargo and power required for engine. Take density of air as 1.2 kg/`m^3`. Assume coefficient of lift for wing at `20^0` angle of attack as 1.42 and coefficient of drag as 0.17. [2073-Shrawan ][5]
