Calculate lift and drag forces and coefficients

1. Consider an aircraft wing the has an area of 500m. The aircraft

is travelling at 200m/s through air that has a density of 0.8

kgm. The lift coefficient of the wing is 0.65. Calculate the lift

force generated under these circumstances.

2. A model wing is placed in a wind tunnel. The velocity of air in

the tunnel is 50m/s with a density of 1.2kqm. The drag force

generated is 6kN over an area of 7m. Calculate the drag

coefficient of the wing.
