  2. Liquid-to-gas ratio - Wikipedia

    en.wikipedia.org/wiki/Liquid-to-gas_ratio

    It is common in wet scrubber terminology to express the liquid flow as a function of the gas flow rate that is being treated. This is commonly called the liquid-to-gas ratio ( L/G ratio ) and uses the units of gallons per 1,000 actual cubic feet or litres per cubic metre (L/m 3 ).

  3. Volumetric flow rate - Wikipedia

    en.wikipedia.org/wiki/Volumetric_flow_rate

    The integration of a flux over an area gives the volumetric flow rate. The SI unit is cubic metres per second (m 3 /s). Another unit used is standard cubic centimetres per minute (SCCM). In US customary units and imperial units, volumetric flow rate is often expressed as cubic feet per second (ft 3 /s) or gallons per minute (either US or ...

  4. Flow coefficient - Wikipedia

    en.wikipedia.org/wiki/Flow_coefficient

    The metric equivalent flow factor (K v) is calculated using metric units: =, where [3]. K v is the flow factor (expressed in m 3 /h), Q is the flowrate (expressed in m 3 /h), SG is the specific gravity of the fluid (for water = 1),

  5. Reynolds number - Wikipedia

    en.wikipedia.org/wiki/Reynolds_number

    Q is the volumetric flow rate (m 3 /s), A is the pipe's cross-sectional area (A = ⁠ πD 2 / 4 ⁠) (m 2), u is the mean velocity of the fluid (m/s), μ (mu) is the dynamic viscosity of the fluid (Pa·s = N·s/m 2 = kg/(m·s)), ν (nu) is the kinematic viscosity (ν = ⁠ μ / ρ ⁠) (m 2 /s), ρ (rho) is the density of the fluid (kg/m 3), W ...

  6. Standard cubic centimetres per minute - Wikipedia

    en.wikipedia.org/wiki/Standard_cubic_centimetres...

    Standard cubic centimeters per minute (SCCM) is a unit used to quantify the flow rate of a fluid. 1 SCCM is identical to 1 cm³ STP /min. Another expression of it would be Nml/min.

  7. Standard litre per minute - Wikipedia

    en.wikipedia.org/wiki/Standard_litre_per_minute

    The standard liter per minute (SLM or SLPM) is a unit of (molar or) mass flow rate of a gas at standard conditions for temperature and pressure (STP), which is most commonly practiced in the United States, whereas European practice revolves around the normal litre per minute (NLPM). [1]

  8. Fixture unit - Wikipedia

    en.wikipedia.org/wiki/Fixture_unit

    The relationship between gallons per minute (gpm) and fixture unit is not constant, but varies with the number of fixture units. For example, 1000 FU is equivalent to 220 US gallons per minute (0.014 m 3 /s) while 2000 FU represents only 330 US gallons per minute (0.021 m 3 /s), about 1.5 times the flow rate.

  9. Parshall flume - Wikipedia

    en.wikipedia.org/wiki/Parshall_flume

    Named after its creator, Dr. Ralph L. Parshall of the U.S. Soil Conservation Service, the Parshall flume is a fixed hydraulic structure used in measuring volumetric flow rate in surface water, industrial discharges, municipal sewer lines, and influent/effluent flows in wastewater treatment plants. The Parshall flume accelerates the flow by ...
