Question 992: Thermodynamics & KTG

Question

Two identical long solid cylinders are used to conduct heat from temperature $T_1$ to temperature $T_2$. Originally, the cylinders are connected in series and the rate of heat transfer is $H$. If the cylinders are connected in parallel, then the rate of heat transfer will be

Accepted Answer

$$ \begin{aligned} &	ext {For two identical solid cylinders, }\ &\begin{array}{ll}  & R_1=R_2=R \ 	herefore & R_s=2 R, R_p=\frac{R}{2} \ 	herefore & \frac{H_p}{H_s}=\frac{R_s}{R_p}=\frac{2 R}{\frac{R}{2}}=4 \ 	ext { Here, } & R_s=H \ 	herefore & H_p=4 H_s=4 H \end{array} \end{aligned} $$
