Two capillaries of same length but different radii $r_1$ and $r_2$ are connected in series. The pressure difference across the first capillary is $\Delta P_1$ and across the second is $\Delta P_2$ . If the rate of flow of liquid through the combination is $Q$ , and $r_1 = 2r_2$ , then the ratio $\Delta P_1/\Delta P_2$ is:
