Solve using the Step$-$by$-$Step method

$4\mathrm{.}5\mathrm{.}5$ For the branching pipe system given in Figure P$4\mathrm{.}5\mathrm{.}5,$

determine the flow to and the elevation of the third reservoir.

Neglect the minor losses and velocity heads. All the pipes are steel

with $f=0\mathrm{.}02.$
