    I assume its 2" copper. The good folks at copper.org have a Calculator and handbook for 5 bucks. I used to have this handy but lent it out and never got it back. Here is the link to all their resources. The one you are looking for is A4005: Copper Tube Sizing Calculator and Handbook http://64.90.169.191/publications/pub_list/plumbing.html

    flow

    The length of the pipe is also critical to make that measurement.
