Question 16 The aerodynamics of a blimp in air are to be tested in a geometrically similar small scale model in a laboratory water tunnel. The model scale is 10:1, the kinematic viscosity of air is 1.46*10-5 m2/s, and the kinematic viscosity of water 1.12*10-6 m2/s. if the prototype is to be tested at a speed of 10 m/s, what speed should the model be tested in water for similitude
