#### Rectangular Contracted Weir Calculator

Rectangular Contracted Weir. This calculator finds the water flow rate for a rectangular contracted weir. A rectangular contracted weir has a rectangular opening where the sides are straight up and down. A contracted weir means that the ditch leading up to the weir is wider than the weir opening itself.. The length is found by measuring the bottom width of the weir and the height is determined ...
