Example: For a spillway crest length/width of 25 ft, Q will vary with H as follows: Discharge as a function of water surface elevation for NRCS and USBR formulas. For the NRCS computations, the mean velocity of approach was assumed to be zero. For the USBR computations, it was assumed that linear interpolation could be used to obtain C from H ...
Refuse chutes or garbage chutes are common in high-rise apartment buildings and are used to collect all the building's garbage in one place. Often the bottom end of the chute is placed directly above a large, open waste container , at times this also includes a mechanical waste compactor .
The ogee crest over-tops a dam, a side channel wraps around the topography of a dam, and a labyrinth uses a zig-zag design to increase the sill length for a thinner design and increased discharge. A drop inlet resembles an intake for a hydroelectric power plant and transfers water from behind the dam directly through tunnels to the river ...
Rumpke planned to nearly double the size of the landfill to produce a 785-acre landfill. [7] Local zoning stymied this expansion, so Rumpke sued the township and obtained a ruling in 2010 that the dump was a public utility and therefore not subject to zoning. [ 7 ]
Some varieties of flumes are used in measuring water flow of a larger channel. When used to measure the flow of water in open channels, a flume is defined as a specially shaped, fixed hydraulic structure that under free-flow conditions forces flow to accelerate in such a manner that the flow rate through the flume can be characterized by a level-to-flow relationship as applied to a single head ...
Using this term, one can calculate many things in the same way as for a round tube. When the cross-section is uniform along the tube or channel length, it is defined as [1] [2] =, where A is the cross-sectional area of the flow, P is the wetted perimeter of the cross-section.
An automated vacuum waste collection system, also known as pneumatic refuse collection, or automated vacuum collection (AVAC), transports waste at high speeds through underground pneumatic tubes to a collection station where the waste is compacted and sealed in containers.
From there it may go onto chutes to guide the viscous concrete directly to the job site. If the truck cannot get close enough to the site to use the chutes, the concrete may be discharged into a concrete pump, connected to a flexible hose, or onto a conveyor belt which can be extended some distance (typically ten or more metres). A pump ...
