First statement.... apples to apples... the difference in PP mixing between a 2640 psi LP 104 and a 3500 psi HP 102 is very significant... you don't do much PP mixing do you? Or you are using a booster.... or you are sending a lot of gas back in the supply cylinders that was unusable because you used a hp tank.Originally posted by pescador775
The differences in partial pressure Nitrox filling a LP tank overfilled to 3000 psi and a HP tank @3500 are insignificant.
A 102 LP tank of 8 inch dia has 25% more drag than a comparable HP steel and 50% more drag than an older steel 72 or SP 3300 psi 72.
Second statement.... Just how much drag is that compared to the total drag of the rig? The drag presented by the rounded end of any of these tanks is minimal compared to the total drag (and certainly that boot on the bottom of your tank is a bigger inducer of drag... not to mention the netting to keep your tank pretty.) 25% of a very minimal amount is a very minimal amount so get specific and quantify the drag for us.
You are right... the LP 104 is heavier to carry out of the water than a HP 102... but that isn't such a big deal to some of us.
