9. A liquid is flowing through a horizontal pipe whose radius is $1.98\times 10^{?2}\mathrm{m}$. The pipe bends straight upward through a height of $10.4\mathrm{m}$ and joins another horizontal pipe whose radius is $3.84\times 10^{?2}\mathrm{m}$. What is the speed of the lliquid in the lower horizontal pipe if the pressure in both horizontal pipes is the same?
