Flow Rate Calculation
The flux or flow rate in cross-flow filtration systems is given by the equation:
- : 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 calculation, flow and/or rate:
“Common sense is the measure of the possible; it is composed of experience and prevision; it is calculation appled to life.”
—Henri-Frédéric Amiel (18211881)
“Our sense of these things changes and they change,
Not as in metaphor, but in our sense
Of them. So sense exceeds all metaphor.
It exceeds the heavy changes of the light.
It is like a flow of meanings with no speech
And of as many meanings as of men.”
—Wallace Stevens (18791955)
“Put God in your debt. Every stroke shall be repaid. The longer the payment is withholden, the better for you; for compound interest on compound interest is the rate and usage of this exchequer.”
—Ralph Waldo Emerson (18031882)
