Please help me with this problem clearly.. One method of calculating the flow in a small stream is to construct a weir across the stream. In a particular situation, a weir is constructed across a small stream. The water passes through a rectangular notch in the weir that is 1.5 meters wide and the height of the water above the bottom of the notch in the weir is 20 centimeters. What is the flow rate of water in this stream?
