0.212 331 gallons per foot.
36.83 u.s. gallons of water in 1 ft. of 30" pipe
About 1,246 Imperial gallons (UK) or about 1,500 US gallons.
A square foot equals an area 12"Wide x 12"Long x 1"Deep. A cubic foot equals an area 12"W x 12"L x 12"D. Therefore, a cubic foot contains 12 square feet. A cubic foot contains 7.48 gallons of water (trust me). You divide a cubic foot by 12 to get 12 square feet, therefore you would divide 7.48 by 12 to get the amount of water contained in 1 square foot. 7.48 divided by 12 equals .623 gallons. For every inch of rainfall there will be .623 gallons of water falling on every square foot.
There need not be any water at all in the pipe. The capacity of the pipe is approx 3.4 Imperial gallons.
One foot of 3 inch pipe will hold approximately 0.625 gallons of water.
A 12 inch diameter round pipe will hold 4.89 UK gallons or 5.88 US gallons per foot.
17,000 gallons
0.212 331 gallons per foot.
It will hold 477.4 gallons of water per 1,300-foot section.
18.264 gallons of water im not tottlaly shur but its my guess
2.75 Imperial gallons.
A 24-inch diameter cylinder holds 23.5 gallons of water per foot of length/height.
1 and 1/2 gallons
Over 9,000.
A 5-inch pipe will hold approximately 0.36 gallons of water per linear foot. This calculation is based on the formula for calculating the volume of a cylinder (V = πr^2h), where the radius (r) is half the diameter of the pipe (2.5 inches) and the height (h) is 1 foot.
A two inch pipe can hold 0.1632 gallons per foot. It takes slightly over 6 feet of two inch pipe to hold one gallon of water.
