Most lumber yards should have it.
The volume of water in 1,500 feet of six-inch pipe is: 294.52 cubic feet or 2,203.2 US gallons.
Three inches
The formula for this goes like this: radius of the pipe squared (32) x pi (3.1416) x length of pipe (12) = volume (amount of water). So 32 x 3.1416 x 12 = 339.2928 or about 339.3 cubic inches.
circumference = 2*pi*radius or pi*diameter
The volume of a 5,000-foot long pipe with a 6-inch diameter is: 981.75 cubic feet.
In the USA, 15mm is half-inch, and 22mm is three-quarters inch. Lengths of pipe nipples in these sizes range from one and a quarter/one and a half, to six inches, in half-inch increments.
About 235 gallons of water.
The pipe's volume is the product of its cross-sectional area and its length. The area of a circle is pi*(radius)^2, so in this case pi*9sq.in. or about 28.3 square inches. Multiply this area by the length of pipe you are using to obtain a volume. A 10 foot length of 6 inch pipe will have 3393 cubic inches of volume or 1.96 cubic feet, or 14.7 US Gallons.

How to make a rocket engine What you need - 5 INCH PVC PIPE - POTASSIUM NITRATE - POWDERED SUGAR - FUSE - CAT LITTER - DRILL - RAM ROD - HAMMER FIRST TAKE YOUR PVC AND POUR A SMALL AMOUNT OF CAT LITTER INTO IT AND THEN TAKE YOUR HAMMER AND RAM ROD AND SMASH DOWN THE CAT LITTER. NOW TO MAKE THE POWDER, TAKE SIX SPOONS OF POTASSIUM NITRATE AND FOUR SPOONS OF SUGAR, PUT IT IN A BOUL AND GRIND IT TOGETHER AND THER'S YOUR POWDER. AND PACK YOUR POWDER IN THE PVC AND THEN CAP IT WITH SOME MORE CAT LITTER. AND YOUR DONE.
