Question $11$

To work the sprayer shown, you partially fill the tank with liquid and use the handle to pump air into the tank; the increased pressure forces the liquid out the end of the spray$-$rod.

Our user fills the $36$ cm high tank half full of water, then uses the handle to pump air into the tank. With the tank resting on the ground, he holds the sprayrod so that it is $183$ cm above the ground and points horizontal. When he pushes the trigger, the water comes out with a speed of $\backslash (9\mathrm{.}3\backslash$mathrm$\{$~m$\}/\backslash$mathrm$\{$s$\}\backslash ).$ The diameter of the tank is much greater than the diameter of the spray$-$rod. Find $[1]$ how far away from the end of the spray$-$rod the water hits the ground and $[2]$ what gauge pressure must he have in the tank so that the water comes out that fast.
