{{quote|A membrane operating with pure feed of water produced a flux of 0.20 \(\text{kg.s}^{-1}\text{.m}^{-2}\); this was with a pressure difference of 20kPa. When operated with a protein-water mixture and a 20 kPa pressure difference, a flux of 0.04 \(\text{kg.s}^{-1}\text{.m}^{-2}\) was measured at steady state. What would be the expected flux for this same protein-water mixture, but at a pressure difference of 30kPa?}} | {{quote|A membrane operating with pure feed of water produced a flux of 0.20 \(\text{kg.s}^{-1}\text{.m}^{-2}\); this was with a pressure difference of 20kPa.
