Experiments were conducted in a wind tunnel with a wind speed of 50 km/hr on a flat plate of size 2 m long and 1 m wide. The density of air is 1.15 kg/m³, the co-efficient of lift and drag are 0.75 and 0.15 respectively. Determine (i) the lift force, (ii) the drag force(iii) the resultant force, (iv) direction of resultant force and (v) the power exerted by air on plate
