Problem $81.$ Consider a steady, incompressible, inviscid flow of water through a diver$-$

gent duct. The inlet velocity and area are $5$ ft$/$s and $10$ ft$2,$ respectively. If the exit area

is $4$ times the inlet area, calculate the water flow velocity at the exit.

$($a$)0$ ft$/$s $$ Ve $<0\mathrm{.}5$ ft$/$s $($b$)0\mathrm{.}5$ ft$/$s $$ Ve $<1$ ft$/$s

$($c$)1$ ft$/$s $$ Ve $<1\mathrm{.}5$ ft$/$s $($d$)1\mathrm{.}5$ ft$/$s $$ Ve $<2$ ft$/$s

$($e$)2$ ft$/$s $$ Ve
