Flow Rate Calculation
The flux or flow rate in cross-flow filtration systems is given by the equation:
in which:
- : liquid flux
- : transmembrane pressure (should also include effects of osmotic pressure for reverse osmosis membranes)
- : Resistance of the membrane (related to overall porosity)
- : Resistance of the cake (variable; related to membrane fouling)
- : liquid viscosity
Note: and include the inverse of the membrane surface area in their derivation; thus, flux increases with increasing membrane area.

Famous quotes containing the words flow, rate and/or calculation:
“Water doesn’t flow if it’s level, and people won’t complain if you treat them on the level.”
—Chinese proverb.
“If we became students of Malcolm X, we would not have young black men out there killing each other like they’re killing each other now. Young black men would not be impregnating young black women at the rate going on now. We’d not have the drugs we have now, or the alcoholism.”
—Spike Lee (b. 1956)
“Common sense is the measure of the possible; it is composed of experience and prevision; it is calculation appled to life.”
—Henri-Frédéric Amiel (1821–1881)
