I looked through the forums and they get a lot into software. How do you manually calculate an expansion loop dimensions? Is there something in ASHRAE for this? An Example is 140 degree F water at 300 gpm in a 4" Black steel sch 40 pipe?

Thanks

Need pipe length (anchor to anchor) to complete the calculation also.
