I am assuming that you are talking about cost? To figure this out I would need the Size and schedule of pipe and the type of electrode or welding you intend to use. What I try to do is calculate lbs. of electrode per inch of weld. Once I have a number per inch on each schedule then I just simply count the inches, do the math and add another 15% for stubs and wastage. I am sure there are many formulas that you could use but I have always relied more on the practical methods and have been ok with those so far. Also unless I know the science of how an answer is obtained I would be leery of the answer and would have to check it practicality before trusting it as well.
