I am working on a problem where I am heating a hollow cylinder from the outside with a NiCr wire which is then insulated. The pipe is cooled by running water through the center of the hollow pipe. I would like to find the heat flux transfer rate outward.
So my set up from the inside to the outside of the pipe is thermocouple 1, thermocouple 2, NiCr wire, insulation, thermocouple 3. Thermocouple 1 and 2 and inside the cylinder wall. Thermocouple 3 is on the outside surface of the insulation. Using temperatures from thermocouple 1 and 2, I can determine the heat transfer rate into the cylinder and then I can subtract that from the power input into the NiCr wire to determine heat transfer rate outwards. However I would like to verify this number using the temperature on the outside surface of the insulation. Is there a way to do this?
Thanks
