    If you have nothing else to go on, many of those where designed for 4fps flow and a 20 degree delta t.

    If you have a 1" supply that would be 8gpm x 20x500 = 80,000 BTU.

    There is a chart in the "conversion factors" tab on the top of the page.

    It is only a rough estimate but it's better than nothing.
