Not to me. Since the hose diameter is constant, there should be no significant turbulence. The real issue is resistance, which limits the ultimate flow rate that hose can carry. Rest assured, a 3/8 hose can carry more gas than you'll ever be able to draw, even one that's 7 feet long. -- Art Greenberg artg@ec*.ne* -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
