## Homework Statement

A broad crested weir model is designed to study the discharge per meter of the prototype. Derive an expression for this discharge using the Buckingham Pi theorem. Assume that the overflowing water sheet is thick so that the surface tension and thus viscosity of the fluid can be neglected. The equation of discharge (Q) for a weir has related with a function of spillway head (H), the gravitational acceleration (g), and the spillway height (h)

## The Attempt at a Solution

in this question , Q (discharge ) cant be chosen as repeating variable , right ? the repeating variables should be H and g , Am i right ? [/B]
