Hydronic resistance of CI Rads?

Does anyone have a rough guideline for calculating the hydronic resistance of cast iron rads. For example a Burnham slim line, four tube, 26" tall, CI Rad with "x" number of sections would be equivalent to "y" feet of 3/4" copper tube? Thanks!

    For hydronic heating purposes the resistance is zero. The main water passage is very large and you'd have to move a ridiculous amount of water to get any resistance.
