Oil flows over a submerged body horizontally at a velocity 15 m/s. The property values for oil are: kinematic viscosity = 3.45 x 10-5 m2/s, density = 833 kg/m3. An enlarged model is used with 8:1 scale in a water towing tank. Determine the velocity of the model to achieve dynamic similarity. If drag force on the model is 3.5 N, predict the drag force on the prototype. Kinematic viscosity of water 1.14 x 10-6 m2/s. =
