Determine the transmembrane pressure required to maintain a flux rate of $250K\frac{g}{h}{m}^2$ in

a reverse osmosis system at $20$degC when the feed solution is $9\%$ sucrose. The

permeability coefficient rate of the membrane is $0\mathrm{.}02k\frac{g}{m^2}$hkPa. Assume that the

density of the liquid is $1081K\frac{g}{m^3}$ at $20$degC and the molecular weight of sucrose is

$342\frac{g}{m}ol.$

Consider Van't hoff and Gibbs equations. Will upvote correct answer!
