I see, ok thanks for your help with the Biot number stuff. So is this the only way of getting a handle on the U value or just the heat loss in general from the small tank experimentally? In my naivety I assumed it would be an easier thing to do that it seems to be...I also assumed that it would...
When calculating the Biot number:
Bi=(h*V)/(A*k)
Am I supposed to take the h value of the water in my smaller tank and the k value of the shell? i.e. ktotal=k1+k2+k3 where k1, k2, k3 are the conductivities of each part of the composite construction?
Thanks for taking the time to reply...
Hi everyone. I am currently carrying out an experiment whereby I have a closed tank of water submerged in a larger tank. The water in the smaller box is heated and I am interested in the heat loss from the tank. I have done a rough theoretical calculation based on U values, where by I obtain...
