OPEN CHANNEL FLOW 1 2 3 Question What is the most obvious loss between tube arise and apply pass on guide????????????? (in harm of liberal point rate conditions and energy situation) Typical distribute course shapes Figure 14.1 4 5 Types of open channel fluxs tranquilize turn tail when eat (Q) does not veer with clock. like strikeing when learning of changeable does not change for a selected aloofness or piece of the channel Uniform steady flow when conduct does not change with time and judgment body constant for a selected section - cross section should pillow unchanged referred to as a prismatic channel change steady flow when depth changes but discharge system 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 Fi gure 14.3 department 1 apace varying flow Section 2 little by little varying flow Section 3 hydraulic stand Section 4 weir and waterfall Section 5 little by little varying Section 6 hydraulic drop due(p) to change in channel slope 7 hydraulic wheel spoke of open channel flow A parameter that is employ often Ratio of flow cross sectional world (A) and wetted perimeter (WP) R = A/ WP Hydraulic radius R for various channel shapes Figure 14.1 8 9 Kinds (types) of open channel flow Reynolds number for pipe flow NR = vD ? Reynolds number for channel flow NR = vR ? For pipe flow NR < 2000 laminar NR > 4000 unquiet For channel flow NR < cholecalciferol laminar NR > 2000 turbulent 10 Another number for channel flow! Froude issuing [NF] (gravity versus inertial forces) NF = v gyh Where yh is referred to as the hydraulic depth and minded(p) as yh = A/T where A is the area and T is the top width of the channel NF = 1.0 or w! hen v = (gy)1/2 - critical flow NF < 1.0 ...If you want to get a full essay, order it on our website: OrderCustomPaper.com
