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 in the atmosphere If the density of air is pand that of the liquid p then for a given piston speed the rate volume per unit time at which the liquid is sprayed will be proportional to a b C Pa Pi Papi Pi V Pa d Pl
