2- A large lawn sprinkler with four identical arms is to be converted into a turbine to generate electric power by attaching a generator to its rotating head. Water enters the sprinkler from the base along the axis of rotation at a rate of 12 kg/s and leaves the nozzles in the tangential direction at a velocity of 45 m/s relative to the rotating nozzle. The sprinkler rotates at a rate of 500 rpm in a horizontal plane. The normal distance between the axis of rotation and the center of each nozzle is 30 cm. Estimate the torque produced. 120.6 N.m 70126 105.5 N.m 109.4 N.m 100.2 N.m 60.5 N.m 2- A large lawn sprinkler with four identical arms is to be converted into a turbine to generate electric power by attaching a generator to its rotating head.
