Problem $2$

Problem Statement:

The force $(l{b}_f)$ exerted by the jet on the wall can be

determined using the following equation:

$F=A{V}^2$

where $F=$Force$(l{b}_f),=$density$(I\frac{b_m}{f}{t}^3),V=$ velocity

$(f\frac{t}{s}),$ and $A=$area$(f{t}^2)$

${}_{\text{w}\text{a}\text{t}\text{e}\text{r}}=62\mathrm{.}4\frac{lbm}{ft{t}^3}$

$g_c=\frac{32\mathrm{.}2lbm*ft}{l{b}_f*s^2}$

$1ft=12in$

A gardener is squirting the side of a house with a

hose. The nozzle of the hose produces a jet of water

with an area of $0\mathrm{.}2in.{?}^2$ with a velocity of $5f\frac{t}{s}.$

Determine the force $(l{b}_f)$ exerted by the jet on the

wall.
