A cylindrical reservoir with a radius R is hang on a string (so it may freely rotate). The reservoir has two nozzles at its bottom part. The nozzles are oriented tangentially to the reservoir surface. They exert thus a torque giving rise to rotations about the vertical axis. Find the angular velocity of the reservoir rotation. Assume that the reservoir radius is much larger than that of the nozzles. The separation between the nozzles is 2L R>r Figure 1: water...
