Figure shows the top view of a cylindrical can mounted on a turntable. The can is filled with water. At a depth h below the water surface are two horizontal tubes of length l and cross-sectional area a, with right-angle bends at their ends. Show that, as the water jets emerge from the tubes, there is atorque tau exerted on the system given by the expression t = 4 rho gh (r+l)a, where rho is the density of the water.
