A lawn sprinkler is constructed from pipe with ¼ -in. inside diameter as indicated in Fig. P5.13R. Each arm is 6 in. in length. Water flows through the sprinkler at the rate of 1.5 lb/s. A force of 3 lb positioned halfway along one arm holds the sprinkler stationary. Compute the angle, θ, which the exiting water stream makes with the tangential direction. The flow leaves the nozzles in the horizontal plane.
