Brian, This must be a troll..... The diameter of the hose will not make any difference until VERY HIGH flow rates (well beyond almost all heavy beathers in distress). Remember, the hose is pressurized with the IP. It is up to the first stage to deliver enough gas, the hose is a very small part of the equation. Steve -----Original Message----- From: Brian Greenberg [mailto:grnbrg@cc*.um*.ca*] Sent: Wednesday, January 27, 1999 10:07 AM To: techdiver@aquanaut.com Subject: Long hose diameter. I am looking at buying a 7 foot hose as part of a gradual evolution from a standard, PADI approved ( :-) ) recreational setup to a more technical rig based in DIR standards. It was recommended by a tech diving friend (who does _not_ DIR, and is quite happy to not do so) that the hose be 1/2 inch diameter, instead of the standard 3/8. His complaint with 3/8 is that it is harder to breath due to the extra turbulence that a long hose adds, and that a 1/2 inch hose, with it's larger diameter would have less turbulence. This seems to make sense. Does anyone have any contrary thoughts, and has anyone tried both and have a definitive answer? -- ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + grnbrg@cc*.um*.ca* + NETDOC Developer, Libraries Electronic + + PGP public key available. + Technologies and Services + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + 83% of all statistics are made up. + -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
