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 connected with 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 20 mm and 1 mm respectively. The upper end of the container is open to the atmosphere. If the piston is pushed at a speed of 5 mm s ^(-1) the air comes out of the nozzle with a speed of :

An ideal liquid of density rho is filled in a horizontally fixed syringe fitted with a piston. There is no friction between the piston and the inner surface of the syringe. Cross-sectional area of the syringe is A. At one end of the syringe, an orifice is made. When the piston is pushed into the syringe, the liquid comes out of the orifice and then following a parabolic path falls on the ground. With what velocity does the liquid come out of the orifice?
