Re: PVC gas tank question. Please help
The volume of one gallon is 230.999952 cubic inches. Find the number of square inches of your desired diameter pipe (Pi x radius squared). Multiply this by the length of your tank to calculate total cubic inches. If you arive at 115 c.i. you have a 1/2 gallon capacity and so on. Good luck!
