About this video: This video tutorial is all about flow over rectangular notch/weir in detail. Here we are going to derive an expression for discharge (Flow rate) over rectangular weir. The rectangular weir is a standard weir frequently used in irrigation channel system for measuring the discharge. It is simple to construct and easy to maintain. Rectangular weir may be fully contracted(end contraction ) using blade or suppressed (no end contraction). The discharge passing through notch or weir is estimated by measuring the head above the crest level. The head is measured above crest level. The head is measured in the upstream when the water surface is by using point gauge or hook gauge or in some cases by automatic water level recorder. Here we derive expression for discharge in two cases: i. Rectangular notch/weir with end contraction ii. rectangular notch/weir without end contraction Again we do considering velocity of approach and without velocity approach.
