Coil heating capacity

Unknown
Unknown
in THE MAIN WALL
I am working on a very old building with no drawings or nameplates on any of the equipment. I am trying to determine the approximate heating capacity of a steam coil in an air handler. I know the square foot face area of the coil, the airflow across the coil is probably 500 fpm, and the steam is at 12 psi. How can I calculate the heating capacity???

Any help would be apprecicated.

    If You Know The...

    ...CFM being moved by the fan, then you can use:

    CFM X 1.08 X delta-T in F all divided by 1000 to get lbs/hr steam required.

    Thanks Tony,

    Is 40 degree air in and 90 degree air out a good assumption?
