The flow rate calculation does not check for unreasonable inputs such as negative values. Instant conversion for units of flow rate by volume.

### Usually it is represented by the symbol q.

**Flow rate units**. The volumetric flow rate in fluid dynamics and hydrometry also known as volume flow rate or rate of fluid flow is the volume of fluid which passes through a given surface per unit time for example cubic meters. Online converter for units of flow rate by volume. The si unit is cubic metres per second.

A cubic metre per second m 3 s 1 m 3 s or cubic meter per second in american english is a derived si unit of flow rate equal to that of a cube with sides one metre 100 centimetres or 39 37 inches in length exchanged or moving each second. List of si units. From acre foot day to trillion cubic foot second and everything in between.

Volumetric flow rate should not be confused with vol. Flow rate mole mole based flow rate. In physics and engineering mass flow rate is the mass of a substance which passes per unit of time.

Sometimes mass flow rate is termed mass flux or mass current see for example schaum s outline of fluid mechanics. Another unit used is standard cubic centimetres per minute. Litres per year gallons per hour cubic inches per second and more to convert.

Everything from micromole second to megamole day. Second m3 s more si units can be found here. You may enter numbers in any units so long as you are consistent l means that the variable has units of length e g.

C 59 f for us. In physics and engineering in particular fluid dynamics the volumetric flow rate is the volume of fluid which passes per unit time. In hydrometry it is known as discharge.

Instantly convert any unit to all others. L 3 t means that the variable has units of cubic length per time e g. The si unit of flow rate volume cubic meter pr.

Units in flow rate calculator. Q va if circular then a π d 2 4. The common symbol is m displaystyle dot m although sometimes μ is used.

In us customary units and imperial units volumetric flow rate is often expressed as cubic feet per second or gallons per minute. Mmscfd million standard cubic feet of gas per day a common volume of gas measure unit abbreviation mmscf scfd standard cubic feet per day gas scfm standard cubic feet per minute gas sm 3 hr standard cubic metre per hour defined at 15 deg. Litres per year gallons per hour cubic inches per second.

In this article the definition is used. Its unit is kilogram per second in si units and slug per second or pound per second in us customary units. Convert volume basis flow rate between several different units.

It is popularly used for water flow especially in rivers and streams and fractions for hvac values measuring air flow. Flow rate volume volume based flow rate. Mass flow rate is defined by the limit.

Flow rate by volume through air and gas flow meters water flow meters and meters for other liquids fluids or flow of objects by mass at various volume versus velocity interval formula calculations.
