What is keeping you from deriving it yourself? Make a small cylindrical mold. Use substances with a known thermal conductivity for end caps. pour some hot water in there with a thermometer to measure the inner temperature while you use an infrared thermometer to measure the outer wall temperature. If you know the total heat tranfered out of the system which you can determine by taking the hot water's initial temperature then taking the temperature an hour later. you can then calculate your btu's/hr. just make sure the water for both tests goes into the mold at the same temperature. Use the equation

Total heat transfered= (thermal conductivity x Area x Differential Temperature)/ Wall thickness.

Total heat transfered is determined by seeing how many btu's/hr are transfered out of the system in a given amount of time.
