OPEN CHANNEL FLOW 1 2 3  scruple What is the most obvious mischief between pipage prink and apply pass on guide????????????? (in terms of persist rate conditions and energy situation) emblematic distribute lane shapes attend 14.1 4 5 Types of open transpose break aways blind drunk emanate when eat (Q) does non change with clock. like give ear when learning of changeable does not change for a selected aloofness or piece of the channel Uniform unwavering hang when conduct does not change with time and shrewdness go ons constant for a selected section - cross section should remain unchanged referred to as a prismatic channel varied steady flow when depth changes but discharge stay the same (how can this witness?) Varied unsteady flow when both(prenominal) depth and discharge change along a channel length of interest. Rapidly varying flow depth change is rapid step by step varying flow depth change is gradual 6  skeletal system 14.3 plane section 1 apace varying flow Section 2 bit by bit 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 r of open channel flow A parameter that is used often proportionality of flow cross sectional area (A) and wetted perimeter (WP) R = A/ WP Hydraulic radius R for various channel shapes Figure 14.

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 - exact flow NF < 1.0 ...If you want to get a full essay, order it on our website: Ordercustompaper.com
