btu per foot 1.25 inch pipe steam base board

Does anny one know the btu per foot for steam base board radiator is 1.25 inch pipe has 3 by 3 inch fins.

not off hand...

and at this time of night I'm not going to do the arithmetic -- besides I'm missing a critical number.

However it's not all that hard: you can figure the effective EDR of the baseboard by determining the surface area.  Each fin, 3" by 3", has an effective surface area of 18 square inches, less the hole in the middle -- say 16 square inches, or 0.1 square feet.  Take that, and multiply it by the number of fins per foot of pipe and add the area of a foot of pipe -- about 0.3 square feet -- and there's the EDR per foot of baseboard.  I don't know how many fins per foot you have, though...
