1. A formula for estimating the volume rate of flow, Q, over the spillway of a dam is Q=C \sqrt{2 g} B\left(H+\frac{V^{2}}{2 g}\right)^{\frac{3}{2}} Where Cis a constant, g is the

acceleration due to gravity, B is the spillway width, H is the depth of water passing over the spillway, and V is the velocity of water just upstream of the dam.What's the unit of C? Would this equation be valid in any system of units? Calculate the discharge Q for B=2.5ft, H=3.5m, V=2.0ft/s, and C=0.55. [Answer: I; 12.25m'/s]
