Q 6.8: An airplane design calls for a lift due to the net force of the moving air on the wing of about 1000N/m^2 of wing area. Assume that air flows past the wing of an air craft with streamline flow. If the speed of flow past the lower wing surface is 160 m/s, what is the required speed over the upper surface to give a lift of 1000N/m^2? The density of air is 1.29 kg/m^3 and assume maximum thickness of wing to be one meter.
