In the frame shown in figure made up of metallic rods of identical size, the ends `A` and `F` are maintained at `T_(1)` and `T_(2)` respectively. The rate of heat flow from `A` to `C` is `omega`. If `C` and `D` are instead maintained at `T_(1)` & `T_(2)` respectively find, find the total rate of heat flow.
