A Pitot tube is shown in figure. Wind blows in the direction shown. Air at inlet `A` is brought to rest, whereas its speed just outside of opening `B` is unchanged. The `U` tube contains mercury of density `rho_(m)`. Find the speed of wind respect to Pitot tube. Neglect the height difference between `A` and `B` and take the density of air as `rho_(a)`.

A spray gun is shown in the figure where a piston pushes air out of a nozzle. A thin tube of uniform cross section is connected to the nozzle. The other end of the tube is in a small liquid container. As the piston pushes air through the nozzle, the liquid from the container rises into the nozzle and is sprayed out. For the spray gun shown, the radii of the piston and the nozzle are 20mm and 1mm respectively. The upper end of the container is open to the atmosphere. If the density of air is rho_a , and that of the liquid rho_l , then for a given piston speed the rate (volume per unit time) at which the liquid is sprayed will be proportional to
