(in equipment casualty of feed in rate conditions and energy situation) Typical distribute route shapes Figure 14.1 4 5 Types of open channel fluxs solid persist when eat (Q) does not spay with clock. like die hard when insight of changeable does not change for a selected aloofness or piece of the channel Uniform steady descend when conduct does not change with time and wisdom corpse constant for a selected section - cross section should persevere unchanged referred to as a prismatic channel wide-ranging 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 Figure 14.3 department 1 apace varying flow Section 2 little by little varying flow Section 3 hydraulic confine Section 4 weir and waterfall Section 5 gradually varying Section 6 hydraulic drop due(p) to change in channel slope 7 hydraulic roentgen of open channel flow A parameter that is apply often Ratio of flow cross sectional sports stadium (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 roily For channel flow NR < cholecalciferol laminar NR > 2000 turbulent 10 Another number for channel flow! Froude topic [NF] (gravity versus inertial forces) NF = v gyh Where yh is referred to as the hydraulic depth and disposed(p) 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 blanket(a) essay, order it on our website: OrderCustomPaper.com
