Question

An aeroplane is passing through an air tunnel. The velocity of air is 70 m/s and 63 m/s respectively at its upper surface of wing and lower surface of wing. Find out the lifting force. Given that total wing area is 2.5 m² and air density is 1.3 kg/m³.

Answer 1

Given v₂ = 70 ms^-1; v₁ = 63 ms^-1;
