PROBLEM 3: Experiments were conducted in a wind tunnel with a wind speed of 50km/h on a flat plate of size 2m long and 1.2m wide. The density of the air is 1.2Kg/m3.The plate is kept at an angle and the co efficient of lift and drag is 0.75 and 0.15 respectively. Determine a) the lift force b) Drag force c) Resultant force d) power expended in overcoming the resistance of the plate.
SOLUTION:
