Ir is required to cut a rectangular canal in a rock formation to carry a discharge of 475 cfs with a velocity of 5 ft/s. Determine the cross-sectional elements if the bottom width is twice the water depth.
A rectangular channel is 4 m wide and 2.5 m deep. The water in the channel is 1. 75 m deep and is flowing at a rate of 21 ls. Determine the area of flow, wetted perimeter, and hydraulic radius. Is the flow laminar or turbulent?
