    Water flow calculation

    I know the water flow calculation for gpm on water. Btuh x 1.25 divided by water delta t x 500. Isnt there a factor for glycol because it doesn't have the heat transfer capabilities of water?

    The "500" comes from the weight of 1 gal water (8.33 pounds) x 60 minutes in an hour multiplied by specific heat, which is 1.0 for water. So if you know the specific heat of your glycol mix, just factor it in and recalculate. Hope this makes sense.
