Constant heat flux vs constant temperature
WebJul 23, 2016 · The OP's choice of setting T t as the constant temperature of the inside wall of the tube is a little awkward. Normally we would set T t = constant for the cooling fluid surrounding the PVC tube. That then requires the calculation of a thermal resistance U of the pipe, as shown here. In the calculation above, U would replace k.
