Q. 36 A water jet (density $=1000 \mathrm{~kg} / \mathrm{m}^{3}$ ) is approaching a vertical plate, having an
orifice at the center, as shown in the figure. While a part of the jet passes through
the orifice, remainder flows along the plate. Neglect friction and assume both the
inlet and exit jets to have circular cross-sections. If $\mathrm{V}=5 \mathrm{~m} / \mathrm{s}, D=100 \mathrm{~mm}$ and
$d=25 \mathrm{~mm}$, magnitude of the horizontal force (in $\mathrm{N}$, rounded off to one decimal
place) required to hold the plate in its position is
