Heat Transfer Conduction
Heat Transfer Conduction
(OP)
When an insulated tank of 306 degrees F has an uninsulated lug sitting on an uninsulated frame. I am trying to determine how far, inch by inch, from the lug to the frame and down, will the temperature decrease. I have been studying the heat transfer equations for conduction, convection, and radiation. I feel that I understand those well, but what I cannot determine is the starting point, exactly how many Btu's the tank would generate through the lug at the vessel wall. The tank is 53-1/4" diameter, a height is 24", and the dome top of the tank is 21-3/8". The vessel wall is 1-1/2". The cross sectional area of the lug one inch from the vessel wall is .63 ft^2. The tank should remain at 306 degrees F and the ambient temperature of the air outside the vessel is 59 degrees F. Both the lug and the vessel are stainless steel with a thermal conductivity value of 9.4 (btu in / ft^2 hr deg F). How do I calculate the maximum Q leaving the vessel wall? An EE will be greatful for your help. Thank you!

Is the process so sensitive to temperature that you have to calculate this? The heat will be disipated very quickly. Only close, very close to the tank it will be hot.

What I was trying to express is that at these temperature gradients, it is very likely that the lug will dissipate most of the heat, as a fin, before it reaches the frame and causes any significant temperature increase in it.
I have not done the calculations, so I could be proven wrong.
