The pipe is a cylinder, with diameter = 30 inches = 1 foot, and height (length) = 25 feet.
Volume of a cylinder = pi R2 L
Volume = pi x (1/2)2 x 25 = (25/4 pi) cubic feet
1 cubic foot = 7.4805 gallons
Volume = (7.4805) x (6.25 pi) = 146.88 gallons(rounded)
The volume of a cylinder is (pi) R2 L .
'R' is the radius of the circular end, and 'L' is the length of the section.
Volume of the concrete pipe = (pi) (1)2 (1) = pi = 3.142 cubic feet = 23.5 gallons (rounded)
Volume = (pi) x (radius)2 x (length) = (pi) x (1/2 ft)2 x (13) = 10.21 cubic feet = 76.377 gallons
That's the volume of the pipe. There's no way for me to know how much water is in it.
A 1.25-foot diameter by 525-foot long pipe will hold up to 4,819.5 US gallons of water.
using the volume for a cylinder is pi*R^2*H, then there is 678 cubic inches which equates to 2.98 gallons
4.1 gallons of water per 25 feet.
11,750.3 gallons per 2,000 feet.
