a nuclear submarine is capable of a top underwater speed of 65km/h.how fast would a 1/20 scale model of the submarine have to be moved through a testing pool filled with seawater for the forces on the submarine and model to be dimensionally similar

Solution

Since the model would be on a scale that is 1/20th the size simply multiply this by the speed.

65(1/20)=3.25km/h
