A reverse osmosis machine for purifying brackish water contains roughly 900,000 hollow threads that allow water to pass through while rejecting the majority of the salt. The fibers have an outside diameter of 85 m, a diameter of 42 m, and a length of roughly 3 ft. When the feed pressure is 400 psig, the average flow through the tubes is 2,000 gal of water every 24 hours. From the feed end to the discharge end, what is the pressure drop within a single fiber
