I have to design accumulator of energy

[patrycja]

I have to design accumulator of energy. Let's consider insulated cylindrical tank with water. How to calculate all heat losses. Should i consider convection between water and wall and then conduction? but what with all sides of tank? It would be easier with single wall. how to get all coefficients? I will really appreciate any help

Welcome to PF!

You'll have to be more specific about the construction of the tank and temperatures involved.
