WebFor a circular conduit, use Equation 6‑17 and Equation 6‑18 to determine the area, A, and top width, T, of flow, respectively. For other shapes, acquire or derive relationships from depth of flow, area, and top width. Equation 6-17. Equation 6-18. where: Anchor: #YFYCSHJD. A = section area of flow, sq. ft. or m 2. WebUniform Flow and its Computations 4.1 Introduction A flow is said to be uniform if its properties remain constant with respect to distance. As mentioned in chapter one of the handout, the term open channel flow in open channel is to mean steady uniform flow. Since Q=AV, it follows that in uniform flow V1=V2=V. thus in uniform flow, depth
