36 cubic feet of water at 6.229 gallons/ cu ft = 224.2 gallons
Up to a maximum of 598.4 gallons of water.
The radius of the pipe is 0.5 feet. The area of the cross-section is pi * r^2 = pi/4 feet^2 The volume is cross-section * length = (pi/4 foot^2) * 1 foot = pi/4 foot^3 There are roughly 7.481 gallons/cubic foot, so the pipe contains (7.481 gallons/(foot^3)) * (pi/4 foot^3) = 7.481 * pi / 4 gallons = 5.875 gallons (not exact)
10,408 gallons.
