A 1/50 scale model is to be used in a towing tank to study the water motion near the bottom of a shallow channel as a large barge passes over. Assume that the models I operated in accordance with the Froude number (page 317 of your books) as the condition for dynamic similarity (i.e. Froude numbers need to be the same for dynamic similarity. The prototype barge moves at a typical speed of 15 knots. (a) At what sped (in ft/s) should the model move? (b) Neat the bottom of the real channel a small particle is found to move at 0.15 ft/s (meaning the fluid velocity is 0.15 ft/s). Determine the velocity in the corresponding point in the prototype channel.
