Jul 26, 2004 #2 CARF Industrial Feb 20, 2003 252 Just depends on a lot of things, the rusted pipes I saw were about 4 mm absolute roughness. See: http://home.hccnet.nl/m.dijk/pressure_drop_calculator/tipsntrics/tipsntrics.html Cheers, CARF Upvote 0 Downvote

This is a fact of the main transmission line from the offshore Dansih gas fields that brings the gas to shore. Best regards Morten Upvote 0 Downvote
