You need to know both length and circumference of the inside part of the pipe.
A 16" by 1,960' pipe holds 20,471.7 gallons water.
A 72-inch pipe 16 feet long holds up to 3,384.1 US gallons of water.
An 8" x 1,300' pipe holds 3,394.5 gallons of water.
100 feet of 3-inch pipe holds 36.73 gallons of water.
A three-inch diameter pipe one foot long holds 0.367 gallon.
1.5-inch by 440 feet of PVC pipe holds 40.4 gallons of water.
much water per foot will a 5 inch pipe hold
The volume of the pipe is 0.2078 gallon per foot of length.I have no idea how much water might be in it.
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.
0.255 gallons per foot of pipe. A 10 ft long pipe that size holds 2.55 gallons.
The capacity of a pipe with a 54 inch inner diameter and a length of 120000 inches is 1,099,306,101 cubic inches, approx = 636,173 cu feet. There may or may not be any water in the pipe!
Depends on the diameter of the pipe and the speed at which the water travels through it.
