Water moves through a constricted pipe in steady, ideal flow. At the lower point shown in the figure below, the pressure is $1\mathrm{.}85{10}^{5}Pa$ and the pipe radius is $2\mathrm{.}90$ cm $.$ At the higher point located at $y=2\mathrm{.}50m,$ the pressure is $1\mathrm{.}21{10}^{5}Pa$ and the plipe radius is $1\mathrm{.}60$ cm $.$

$($a$)$ Find the speed of flow in the lower section. $\frac{m}{s}$

$($b$)$ Find the speed of flow in the upper section. $\frac{m}{s}$

$($c$)$ Find the volume flow rate through the pipe.
