(See Fluids in the News article titled “Ice Engineering,” Section 7.9.3.) A model study is to be developed to determine the force exerted on bridge piers due to floating chunks of ice in a river. The piers of interest have square cross sections. Assume that the force, R, is a function of the pier width, b, the thickness of the ice, d, the velocity of the ice, V, the acceleration of gravity, g, the density of the ice, ρi, and a measure of the strength of the ice, Ei, where Ei has the dimensions FL-2 (a) Based on these variables determine a suitable set of dimensionless variables for this problem. (b) The prototype conditions of interest include an ice thickness of 12 in. and an ice velocity of . What model ice thickness and velocity would be required if the length scale is to be 1/10? (c) If the model and prototype ice have the same density, can the model ice have the same strength properties as that of the prototype ice? Explain
