Is there a relation between average water temperature and over?

Does anyone knows the relation between temperature and height in water. . .?

• Answer:

  Gotcha. The second law of thermodynamics states: The entropy of an isolated system not in equilibrium will tend to increase over time, approaching a maximum value at equilibrium. Simply put, that means that the temperature between the top and the bottom of the talk will equilize over time, and and it will do it in a way that approaches linearity. Therefore, we can reasonably expect that if the top of the talk measures 70 degrees and the bottom measures 50 degrees, the middle will be close to 60 degrees. An equation for this would be: Tx = Tt + (x/H) * (Tt-Tb) Definitions: Tx = temp at x feet from the top of the tank Tt = temp at the top of the tank x = the number of feet from the top of the tank H = the height of the tank Tb = temp at the bottom of the tank This assumes an ideal system. If your tank is partially in the sun, or partially underground, these calculations become more complex. In that case, if temperature is critical, you may consider a system that would mix the water an bring the system to equilibrium at a single temperature. Cheers!
