flow rate

Thesaurus

Noun

flow rate - the amount of fluid that flows in a given timerate of flow, flowcardiac output - the amount of blood pumped out by the ventricles in a given period of time; "a resting adult has a cardiac output of about three quarts a minute"rate - a magnitude or frequency relative to a time unit; "they traveled at a rate of 55 miles per hour"; "the rate of change was faster than expected"

Flow Rate

flow rate

[′flō ‚rāt] (fluid mechanics) Also known as rate of flow. Time required for a given quantity of flowable material to flow a measured distance. Weight or volume of flowable material flowing per unit time.

Flow Rate

in hydraulics, the volume of fluid flowing through a cross section of a stream per unit time. The flow rate Q of a fluid for a given cross section ω is determined by the formula

Q = ∫_ωu dω

where u is the flow velocity within the limits of d, an elementary segment of the cross section. In steady flow, the flow rate of a dropping liquid is constant along a given stream. The average flow velocity of the fluid can be determined from the known values of the flow rate and cross-sectional area: v = Q/ω. The mass of fluid flowing per unit time through a cross section of the stream is called the mass flow rate M. This rate is related with the volume flow rate by the equation M = ρ Q, where ρ is the density of the fluid. The flow rate of a fluid is measured with water meters, measuring spillways, hydrometers, rate-of-flow meters, and other instruments.
