QUESTION $19$

Consider a reverse osmosis system for the desalinization of brackish ground water with a water temperature of $20C.$

B: If the coefficient of water permeation for a reverse osmosis membrane is $14\mathrm{.}07{10}^{-3}\frac{L}{m^2*hr*KPa},$ then the transmembrane pressure in KPa needed to produce a water flux through the membrane of $20\frac{L}{m^2*hr}$ is most nearly:

a$)1420$

b$)142$

c$)1891$

d$)1500$

d$)1500$ KPa

c$)1891$ KPa

a$)1420$ KPa

b$)142$ KPa
