Carl Green Posted January 28, 2016 Posted January 28, 2016 Okay all you smartypantseses out there. I've been trying to figure this out on my own for a while now but I've just about reached the limit of time I'm willing to spend on figuring this out so I'm outsourcing. I need to determine the amount of pure O2 flow, compressed at 8psi (0.5515bar), in liters/minute through a 3ft/1M length of rubber tube with a 3/16"(4.7625) ID. $5 in BTC for the first person to get me the number. (more if you help me make an excel file with a built in calculator so I can play with the length and diameter variables)

Carl Green Posted January 29, 2016 Author Posted January 29, 2016 Thanks for the link but that was for calculating through an orifice. Here's the tl;dr backstory. I have a glassblowing torch that I'm trying to feed from a set of regulators mounted right by the torch. It requires 2 sets each of oxygen and propane gases; one for an inner stage/smaller flame, and another set for an outer flame. The torch manufacturer spec's it as needing a total oxygen flow rate of 32 liters/min at 8psi. That gets split by the two stages into 12 and 21 l/m with the pressure remaining the same. I'm trying to use the smallest diameter hose possible (3/16") for flexibility purposes and I was looking to verify the hose size and length as being able to accommodate that flow rate.
