Flow rate: The time required for a volume of groundwater to move between points. Typically groundwater moves very slowly-sometimes as little as inches per year.
Fresh water: Water with less than 0.5 parts per thousand dissolved salts.

Flow Rate - The rate, expressed in gallons -or liters-per-hour, at which a fluid escapes from a hole or fissure in a tank. Such measurements are also made of liquid waste, effluent, and surface water movement.
flow rate Fluid movement in volume per time, such as the rate expressed in gallons or liters per hour at which a liquid passes through a channel.
Flow Rate
The rate at which a fluid escapes from a unit area. Such measurements are made of liquid waste, effluent, and surface water movement.

Overflow rate: One of the guidelines for design of the settling tanks and clarifiers in a treatment plant to determine if tanks and clarifiers are used enough.
PEAK DISCHARGE (FLOW RATE)
The maximum instantaneous rate of flow during a storm, usually in reference to a specific design storm event.
PERCENT AREA METHOD ...
flux (of a quantity)
Flow rate of an entity through a cross-section perpendicular to the flow divided by the cross-sectional area.
Heat used by the customer is metered, usually as hot water flow rate and temperature difference between outflow and return. Fully responsible for ensuring continuous operation and suitable quality fuel supply.
Gas Sorption: Devices used to reduce levels of airborne gaseous compounds by passing the air through materials that extract the gases. The performance of solid sorbents is dependent on the airflow rate, concentration of the pollutants, ...
Composite Sample: A series of water samples taken over a given period of time and weighted by flow rate.
Weir: 1. A wall or plate placed in an open channel to measure the flow of water. 2. A wall or obstruction used to control flow from settling tanks and clarifiers to ensure a uniform flow rate and avoid short-circuiting. (See: short-circuiting.) ...
Shock load Influent wastewater entering the plant which has an unusually high organic content and/or high flow rate.
...
In pipelines, the time is calculated by dividing the internal volume of the pipe by he maximum hourly flow rate; within mixing basins and storage reservoirs it is determined by tracer studies of an equivalent demonstration.
Typically the orifice meter consists of a thin plate with a square-edged, concentric and circular orifice. The pressure drop of the jet effect across the orifice is proportional to the flow rate.
Generally, the retention time of a flocculation basin is at least 30 minutes with speeds between 0.5 feet and 1.5 feet per minute (15 to 45 cm / minute). Flow rates less than 0.5 ft/min cause undesirable floc settlement within the basin.
