February 1, 2021 Q3 (35 pts.) Water flows over the spillway of a dam as illustrated in figure below. Assume that the flowrate, Q, over the spillway depends on the head, H, width, b, acceleration of gravity, g, fluid density, p, and fluid viscosity, u. For this problem using H, g, and p as repeating variables, find only one of the dimensionless parameters which includes the discharge, Q. H)
