You are using a rectangular sharp$-$crested weir to measure flow in a river that crosses your property. The weir is $5$ ft across and $3$ ft high. A$)$ What is the flow rate when the depth of water crossing the crest is $6?$ B$)$ Your neighbor uses a sharp$-$crested triangular weir with $=90$ to measure the flow rate of the same stream when it crosses her property. Neglecting incidental losses between your property and hers, what is the water height in her weir for this flow rate? Use the appropriate weir correction factors given in the videos.
