In hydrometry, the volumetric flow rate is known as discharge. Volumetric flow rate should not be confused with volumetric flux, as defined by Darcy's law and represented by the symbol q, with units of m 3 /(m 2 ·s), that is, m·s −1. The integration of a flux over an area gives the volumetric flow rate. The SI unit is cubic metres per ...
Standard cubic feet per minute (SCFM) is a volumetric flow-rate corrected to a set of "standardized" conditions of pressure, temperature, and relative humidity. The standard conditions are often defined as 14.7 psia, temperature 70°F and relative humidity 0%, but the conditions may vary depending on the "standard" used.
In fluid dynamics, the volumetric flux is the rate of volume flow across a unit area (m 3 ·s −1 ·m −2), and has dimensions of distance/time (volume/(time*area)) - equivalent to mean velocity. The density of a particular property in a fluid's volume, multiplied with the volumetric flux of the fluid, thus defines the advective flux of that ...
Mass flow rate (ṁ or μ), the mass of a substance which passes per unit of time Volumetric flow rate ( Q or V ˙ {\displaystyle {\dot {V}}} ), the volume of fluid which passes per unit time Discharge (hydrology) ( Q ), volume rate of water flow that is transported through a given cross-sectional area, such as a river
Energy flow rate is usually derived from mass or volumetric flow rate by the use of a flow computer. In engineering contexts, the volumetric flow rate is usually given the symbol Q {\displaystyle Q} , and the mass flow rate, the symbol m ˙ {\displaystyle {\dot {m}}} .
A variation in standard temperature can result in a significant volumetric variation for the same mass flow rate. For example, a mass flow rate of 1,000 kg/h of air at 1 atmosphere of absolute pressure is 455 SCFM when defined at 32 °F (0 °C) but 481 SCFM when defined at 60 °F (16 °C).
Volume flux most often refers to: Volumetric flow rate , the volume of fluid which passes per unit time Volumetric flux , the rate of volume flow across a unit area
In oceanography, the sverdrup (symbol: Sv) is a non-SI metric unit of volumetric flow rate, with 1 Sv equal to 1 million cubic metres per second (264,172,052 US gal/s). [1] [2] It is equivalent to the SI derived unit cubic hectometer per second (symbol: hm 3 /s or hm 3 ⋅s −1): 1 Sv is equal to 1 hm 3 /s.
