The resistance created by waves on a 120-m-long ship is tested in a channel using a model that is 4 m long y part a if the ship travels at 70 km/h. what should be the speed of the model?

Explanation:

given,

length of the ship = 120 m

length of model of the ship = 4 m

Speed at which the ship travels = 70 km/h

speed of model = ?

by using froude's law

for dynamic similarities

hence, the velocity of model will be 12.78 km/h
