An airplane wing with chord length L = 1.5m and span S = 9m is designed to move through standard air at a speed u = 7.5m/s. A 1/10 scale model of this wing is to be used in a water tunnel to perform measurements of the lift force F. (1) Using the method of repeating variables, determine the expression of the dimensionless groups relevant in this application (2) What speed is necessary in the water tunnel to achieve dynamic similarity? (3) What will be the ratio of forces measured in the model flow to those on the prototype wing?
