Question

Experiment were conducted in a wind tunnel with wind speed of 50 km/hr on a flat plate 2 m long and 1 m wide. The mass density of air is 1.15 kg/m3, and plate is kept at such an angle that the coefficients of lift and drag are 0.75 and 0.15 respectively. Determine the lift force, drag force, resultant force and power exerted by the air stream on the plate.
