Question

A large lawn sprinkler with two identical arms is used 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 5 gal/s and leaves the nozzles in the tangential direction. The sprinkler rotates at a rate of 180 rpm in a horizontal plane. The diameter of each jet is 0.7 in, and the normal distance between the axis of rotation and the center of each nozzle is 2 ft.

1. Now, if the rotating head somehow gets stuck, determine the moment acting on the head. Take the density of water to be 62.4 lbm/ft^3.

Answer 1

323.97 lbf/fr
