$($a$)$

What is the pressure drop $($in N$/$m$2)$ due to the Bernoulli effect as water goes into a $2\mathrm{.}90$ cm diameter nozzle from a $9\mathrm{.}40$ cm diameter fire hose while carrying a flow of $35\mathrm{.}0$ L$/$s$?$

N$/$m$2$

$($b$)$

To what maximum height $($in m$)$ above the nozzle can this water rise? $($The actual height will be significantly smaller due to air resistance.$)$

m
