Modern airplane design calls for a lift, due to the net force of the moving air on the wing, of about 2000 N per square meter of wing area. Assume the air flows past the wing of an aircraft with streamline flow. If the speed of flow past the lower wing surface is 120m/s, what is the required speed over the upper surface to give a lift of 2000 N/m^2? The density of air is 1.20 kg/m^3
