Density and Pressure

Density and Pressure problem 2

A liquid sprayer is taken - see picture. The sprayer creates a vacuum by means of an airflow created by squeezing a rubber pump. The undercoat lifts the liquid from the container, pushes it into a horizontal tube, and disperses it - see picture. What must be the minimum velocity of the airflow to raise the liquid by 6 cm? The density of the liquid is and of the air is . The pressure above the liquid in the tank is equal to the normal air pressure.
