Physics - Fluid Question with Solution | TestHub

A certain fire extinguisher consists of a large sealed tank with a thin tube leading from the bottom of the tank to an exit nozzle; the air above the liquid in the tank is at an overpressure ${\mathrm{p}}_{\text{tank }}$ with respect to atmospheric pressure ${\mathrm{p}}_0$. The exit nozzle is at the same level as the top of the liquid; both are a distance y above the bottom of the tank (see figure). The liquid has density $\rho$. Find an expression for the speed of the stream of liquid emerging from the nozzle.
