Water moves through a constricted pipe in steady, ideal flow. At the lower point shown in the figure below, the pressure is

$1\mathrm{.}85\backslash$times $10^(5)$Pa and the pipe radius is $2\mathrm{.}70$ cm $.$ At the higher point located at y$=2\mathrm{.}50$m$,$ the pressure is $1\mathrm{.}22\backslash$times $10^(5)$Pa and

the pipe radius is $1\mathrm{.}60$ cm $.$

$($a$)$ Find the speed of flow in the lower section.

$($m$)/($s$)$

$($b$)$ Find the speed of flow in the upper section.

$($m$)/($s$)$

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

$($m$^(3))/($s$)$
