A reverse-osmosis unit for purifying brackish water has about 900,000 hollow fibers that permit the diffusion of water but reject most of the salt. The fibers are 85 J-lm in outside diameter, 42 J-lm in inside diameter, and about 3 ft long. The average flow through the tubes is 2000 gal of water every 24 h when the feed pressure is 400 psig. What is the pressure drop withi'Il: an individual fiber from the feed end to the discharge end?
