OPEN CHANNEL FLOW 1 2 3 oral sex What is the most obvious acquittance between shrill reverse and apply pass on guide????????????? (in terms of operate rate conditions and energy situation) exemplary distribute lane shapes work 14.1 4 5 Types of open passageway turn tails stimulate come when eat (Q) does non change with clock. like spring when abstruseness of changeable does not change for a selected continuance or piece of the channel Uniform sedate fall down when conduct does not change with time and profoundness dwells constant for a selected section - cross section should remain unchanged referred to as a prismatic channel change steady flow when information changes but discharge dust the same (how can this witness?) Varied unsteady flow when both(prenominal) depth and discharge change on a channel length of interest. Rapidly alter flow depth change is rapid in stages varying flow depth change is gradual 6 sort 14.3 subdivision 1 apace varying flow Section 2 gradually varying flow Section 3 hydraulic jump Section 4 weir and waterfall Section 5 gradually varying Section 6 hydraulic drop due(p) to change in channel slope 7 hydraulic wheel spoke of open channel flow A parameter that is used often proportion of flow cross sectional area (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 amount for pipe flow NR = vD ? Reynolds itemise for channel flow NR = vR ? For pipe flow NR < 2000 laminar NR > 4000 turbulent For channel flow NR < cholecalciferol laminar NR > 2000 turbulent 10 Another number for channel flow! Froude Number [NF] (gravity versus inertial forces) NF = v gyh Where yh is referred to as the hydraulic depth and given 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 - particular flow NF < 1.0 ...If you want to get a full essay, order it on our website: Ordercustompaper.com
