Interactive Knowledge Check

According to ASTM D4516, when seawater temperature drops from 30°C to 20°C with feed pressure held constant, what happens to the permeate water viscosity and driving pressure?

Viscosity decreases, causing permeate flow to increase.Water viscosity increases, requiring higher net driving pressure to maintain target flux. (Correct)
