Narrowing of a conduit, called Venturi, produces low pressure in the throat, which allows you to suck fluid from a reservoir, as it is shown in the Figure. Through the equation of Bernoulli, get an expression for the minimum V1 speed needed to bring the fluid to the Throat.

A converging-diverging tube, called a venturi, develops a
low-pressure airflow in the throat capable of sucking a heavier
fluid up a reservoir, as shown in the figure. This is the working
principle of paint spraying guns. The specific masses of air and
liquid are respectively , while the throat and discharge
diameters in the atmosphere are respectively D1 and D2.
If the elevation height above the liquid level in the reservoir is
h and the gravitational acceleration is g, deduce...
