Rectangular Contracted Weir Calculator

Rectangular Contracted Weir. This calculator finds the water flow rate for a rectangular contracted weir. A rectangular contracted weir has a rectangular opening where the sides are straight up and down. A contracted weir means that the ditch leading up to the weir is wider than the weir opening itself.. The length is found by measuring the bottom width of the weir and the height is determined ...

Flume - Wikipedia

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 (level) measurement within ...

How Streamflow is Measured - USGS

Mar 03, 2019· The discharge measurement. Discharge is the volume of water moving down a stream or river per unit of time, commonly expressed in cubic feet per second or gallons per day. In general, river discharge is computed by multiplying the area of water in a channel cross section by the average velocity of the water in that cross section:

A free chlorine level of 0.5 mg/L of free chlorine will be enough residual to maintain the quality of water through the distribution network, but is most likely not adequate to maintain the quality of the water when this water is stored in the home in a bucket or jerry can for 24 hours. Thus, the SWS Program recommends for dosage testing that:

Mill (grinding) - Wikipedia

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

Sluice gate flow metering is often used to measure flow rate in open channels. Sluice gates are also often used to modulate flow. The sluice gate flow rate measurement is based on the Bernoulli Equation and can be expressed as: 1/2 ρ v 1 2 + ρ g h 1 = 1/2 ρ v 2 2 + ρ g h 2 (1) where. h = elevation height (m) ρ = density (kg/m 3)
