Hello - this is a simple yet little tricky formula. First you need to find the volume of the pipe then convert it to gallons. 1 cubic foot = .1337 gallon

(pi x (radius (squared))= area of the circle x length = (volume in cubic inches / 1728 = cubic feet) / .1337 = gallons

3.14 x (2 x 2) =12.566370614359172953850573533118 x 12 = 150.79644737231007544620688239742 / 1728 = 0.087266462599716478846184538424421 / .1337 = 0.65270353477723619181888211237413 gallons

So rounded out it is .65 gallons
