Question

Chapter 2: Dimensional Analysis Exercise!l 2019 1. Amirul Asyraf's team is to design a human-powered submarine for a design competition The overall length of the prototype submarine is 2.24 m, and its student designers hope that it can travel fully submerged through water at 0.560 m/s, The water is freshwater (a lake) at T-15°C. The design team builds a one-eighth scale model to test in ther university's wind tunnel. A shield surrounds the drag balance strut so that the aerodynamic drag of the strut itself does not influence the measured drag The air in the wind tunne is at 25 C and at one standard atmosphere pressure. At(what air speed do they need to run the wind tunnel in order to achieve similarity? Hini Por water at T 15C and atmospheric pressure, p 9991 kg/m3 and y1.138 x 10-kg/m-s. For air at T: 2500 and atmospheric pressure p L184 k/m3 and 9 x 10*k/m s)
