Water Undergoes Viscous Flow Through Two Pipes with the Same $0.400 \mathrm{~cm} 3 / \mathrm{s}$

Water undergoes viscous flow through two pipes with the same pressure difference between the ends. Pipe 1 has three times the diameter and twice the length of pipe 2 . If the flow rate through pipe 1 is $0.400 \mathrm{~cm} 3 / \mathrm{s}$ , then what is the flow rate through pipe 2 ?

A) $8.33 \times 10^{-3} \mathrm{~cm}^{3} / \mathrm{s}$
B) $10.80 \times 10^{-3} \mathrm{~cm}^{3} / \mathrm{s}$
C) $6.22 \times 10^{-3} \mathrm{~cm} 3 / \mathrm{s}$
D) $9.88 \times 10^{-3} \mathrm{~cm}^{3} / \mathrm{s}$
E) $7.78 \times 10^{-3} \mathrm{~cm}^{3} / \mathrm{s}$
