how do I determine the volume of 600' of 1 1/4 schedule 40 PVC?

.7854 x D squared x length

high school math.

cross section is pi ( 3.14149) times radius squared. So mutilpy 5/8" x 5/8" x 3.14149. Multiply that times the length ( 7200 inches). That gives you the volume in cubic inches. Divide by 231 for gallons.

Thank you. High scool math was a problem for me 30 years ago too.
