  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. 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]

  5. 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),

  6. 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 ...

  7. Parshall flume - Wikipedia

    en.wikipedia.org/wiki/Parshall_flume

    For free flow, the equation to determine the flow rate is simply Q = CH a n where: Q is flowing rate (ft 3 /s) C is the free-flow coefficient for the flume (see Table 1 below) H a is the head at the primary point of measurement (ft) (See Figure 1 above) n varies with flume size (see Table 1 below) Parshall flume discharge table for free flow ...

  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. Standard cubic feet per minute - Wikipedia

    en.wikipedia.org/wiki/Standard_cubic_feet_per_minute

    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). Due to the variability of the definition and the consequences of ambiguity, it is best engineering practice to state what standard conditions are used when communicating ...
