Problem 7-37

A student team is to design a human-powered submarinefor a design competition. The overall length of the prototypesubmarine is 4.85 m, and its student designers hopethat it can travel fully submerged through water at 0.440 m/s.The water is freshwater (a lake) at T 5 15C. The designteam builds a one-fifth scale model to test in their universityswind tunnel (Fig. P737). A shield surrounds the drag balancestrut so that the aerodynamic drag of the strut itself does notinfluence the measured drag. The air in the wind tunnel is at 25C and at one standard atmosphere pressure. At what airspeed do they need to run the wind tunnel in order to achievesimilarity? Answer: 30.2 m/s
