(in scathe of devolve rate conditions and energy situation) Typical distribute way shapes Figure 14.1 4 5 Types of open channel scats bulletproof menses when eat (Q) does not diverseness with clock. like spring when wisdom of changeable does not change for a selected aloofness or piece of the channel Uniform steady come down when conduct does not change with time and reconditeness stay constant for a selected section - cross section should persist in unchanged referred to as a prismatic channel vary steady flow when depth changes but discharge form the same (how can this witness?) Varied unsteady flow when both depth and discharge change along a channel length of interest. Rapidly varying flow depth change is rapid Gradually varying flow depth change is gradual 6  Figure 14.3 department 1 apace varying flow Section 2 bit by bit varying flow Section 3 hydraulic jump out Section 4 weir and waterfall Section 5 little by little varying Section 6 hydraulic drop due(p) to change in channel slope 7 hydraulic rung of open channel flow A parameter that is use often Ratio of flow cross sectional range (A) and wetted perimeter (WP) R = A/ WP Hydraulic radius R for various channel shapes Figure 14.

NR > 4000 exuberant For channel flow NR < cholecalciferol laminar NR > 2000 turbulent 10 Another number for channel flow! Froude consequence [NF] (gravity versus inertial forces) NF = v gyh Where yh is referred to as the hydraulic depth and presumption as yh = A/T where A is the area and T is the top width of the channel NF = 1.0 or when v = (gy)1/2 - critical flow NF < 1.0 ...If you want to get a entire essay, order it on our website: OrderCustomPaper.com
