Water flows through a multi$-$sectional pipe placed horizontally on the ground. The velocity is $\backslash (3\mathrm{.}0\backslash$mathrm$\{$~m$\}/\backslash$mathrm$\{$s$\}\backslash )$ at the entrance and $\backslash (1\mathrm{.}2\backslash$mathrm$\{$~m$\}/\backslash$mathrm$\{$s$\}\backslash )$ at the exit. What is the pressure difference between these two points? Neglect friction.

$110$ kPa

$3\mathrm{.}8$ kPa

$2\mathrm{.}3$ kPa

$28$ kPa
