G"the force exerted on a bridge pier in a river" is to be tested in a 1: 10 scale model using water as the working fluid. in the prototype the depth of water is 2.0 m, the velocity of flow is 1.5 m/s and the width of the river is 20 m. of the hydrodynamic force on the model bridge pier is 5 n, what would it be on the prototype? (hint: pressure ratio is equal to the length-scale ratio) (5 points; ans: 5000 n)
