In a modified version of a problem from the text, the rectangular channel has a width of 3 m and the depth of flow is 2.1 m. The top of the weir is located 1.0 m above the channel bottom. Determine the volumetric flow of water over the rectangular sharp-crested weir using the appropriate weir equation from the FE handbook. Units should be m3/s and answer should be to 3 significant figures.
