The circumference of 12-inch pipe is: 37.7 inches. (C = d x Pi)Since 12 inch pipe is a nominal size and its outside diameter is 12.75 inches, the circumference of 12 inch pipe actually is : 40.035 inches
The internal diameter of the pipe times pi times its length will yield the volume it can contain. The outer diameter of the pipe times pi times its length will yield the volume that the pipe will displace when it is submerged or buried. The volume the pipe will displace minus the volume it will contain will yield the volume of material that makes up the pipe.

Well the UPC (uniform plumbing code) has the information but your drain line going outside the building and your vent line going outside the roof has to meet the same square inches. So if you have a main dran line that is 4" running outside the building then your must have enough square inches of pipe going threw the roof in example ( you would need four 2" vent pipes to equal one 4" pipe). Trailer homes don't follow the code and they go by the AWC (almost works code)
