# Ultrafiltration Membrane Design Calculator

## Water Filtration and Purification

Solving membrane water flux.

#### Inputs:

 pressure differential (ΔP) pascal atmosphere bar dyne/centimeter^2 foot of water inch of mercury inch of water kilonewton/meter^2 millibar millimeter of mercury newton/meter^2 pound/foot^2 pound/inch^2 torr osmotic pressure differential (Δπ) pascal atmosphere bar dyne/centimeter^2 foot of water inch of mercury inch of water kilonewton/meter^2 millibar millimeter of mercury newton/meter^2 pound/foot^2 pound/inch^2 torr gel layer resistance (RS) gram-centimeter/gmol-second membrane resistance (RM) gram-centimeter/gmol-second

 |

#### Conversions:

 pressure differential (ΔP) = 0 = 0 dyne/centimeter^2 osmotic pressure differential (Δπ) = 0 = 0 dyne/centimeter^2 gel layer resistance (RS) = 0 = 0 gram-centimeter/gmol-second membrane resistance (RM) = 0 = 0 gram-centimeter/gmol-second

#### Solution:

 membrane water flux (JW) = HAS NOT BEEN CALCULATED
