In physics and engineering, in particular fluid dynamics, the volumetric flow rate (also known as volume flow rate, or volume velocity) is the volume of fluid which passes per unit time; usually it is represented by the symbol Q (sometimes ˙).

The volumetric flow rate (V) of a system is a measure of the volume of fluid passing a point in the system per unit time. The volumetric flow rate can be calculated as the product of the cross sectional area (A) for flow and the average flow velocity (v).

Flow rate and velocity are related by \(Q = A\overline{v}\) where \(A\) is the cross-sectional area of the flow and \(v\) is its average velocity. For incompressible fluids, flow rate at various points is constant.

2018年12月7日 · Volumetric flow rate equation. The basic volumetric flow rate equation to determine volumetric flow is: Q = vA. Where, Q is volumetric flow in m 3 /s; v is the flow velocity in m/s; A is area in m 2; A simple example might be water flowing through a rectangular channel that has a 10cm by 5cm cross-section at a velocity of 5 m/s.

Determine the volumetric and mass flow rate of a fluid with our flow rate calculator.

2020年12月15日 · Volume flow rate offers a measure of the bulk amount of fluid (liquid or gas) that moves through physical space per unit time. The volume flow equation is Q = AV, where Q = flow rate, A = cross-sectional area, and V is average fluid velocity.

Volume flow rate is the fluid's volume which flows per unit time. It is generally denoted by the symbol ''Q'' (occasionally ''V''). The SI unit of volume flow rate is cubic metres per second.

This flow rate calculator uses flow velocity and cross-sectional flow area data to determine the volumetric flow rate of liquid. You can calculate the flow rate in five simple steps: Select the shape of the cross-section of the channel; Input all the measurements required to compute the cross-sectional area; Input the average velocity of the flow

Volume flow rate is represented by the symbol Q, with unit as m3s−1 i.e. cubic meters per second. Therefore the Volume Flow Rate Formula can be written as: VolumeFlowRate = (variationofvolume) (variationoftime) Mathematically, Q = ΔVol Δt. Where, Q.1: A fluid is flowing through a tube which has a transverse area of 0.3 square meters.

Flow rate can be calculated using the formula: \text{Flow rate}=\cfrac{\text{Volume}}{\text{Time}}. What units are used for flow rate? Common units for flow rate include liters per second (L/s), gallons per minute (GPM), and cubic meters per hour (m^3/h).
