The article was reworked from Nephron's inital version to match equations in the Seader & Henley reference. The main differences include the inclusion of a concentration difference driving force and changing the flow from mass (kg) to amount (moles). Most commonly flow rates used in chemical engineering are in moles, however, the conversion between mass and moles is trival (multiply or divide by the molecular weight. Since mass transfer is a flow of material, the relationship should include "flow = (driving force)/(resistance)" as it now does. Flow is the mass transfer rate, driving force is the concentration difference, and the resistance is the inverse of transfer area. - BeastRHIT06:24, 9 July 2006 (UTC)[reply]
