Philippine Aviation design calls for a lift due to the net force of moving air on the wing of about 2000N per m2 of wing area. Assume that air flows past the wing of an aircraft with streamline flow. If the speed of the flow past the upper surface is 120m/s, what is the required speed over the upper surface with a lift of 2000N/m3? The density of the air is 1.20kg/m3.
