1.	The three rods shown in figure have identical dimensions. Heat flows from the hot end at a rate of 40 W in the arrangement (a). Find the rates of heat flow when the rods are joined as in arrangement (b). (Assume kAl=200 W/m ∘C and kCu=400 W/m ∘C)
Answer» The three rods shown in figure have identical dimensions. Heat flows from the hot end at a rate of $40 W$ in the arrangement (a). Find the rates of heat flow when the rods are joined as in arrangement (b). (Assume $k_{A l} = 200 W/m^{\circ} C$ and $k_{C u} = 400 W/m^{\circ} C$ )
