Critical radius of insulation
In class, we were taught that the critical radius of insulation (found by differentiating thermal resistance WRT outer radius and setting to zero) gives a minimum resistance and thus and maximum heat loss- i.e. it's not always productive to insulate your pipe.
but could it not also give a maximum resistance and therefore a minimum heat loss? differentiating again surely would tell you when it would be minimum and maximum? |
