A sprinkler essentially consists of a pipe AB mounted on a hollow shaft. The water comes in the pipe at O and goes out the nozzles at A and B, causing the pipe to rotate. Assume the the particles of water move through the pipe at a constant rate relative to the pipe of 2 ft/s and that the pipe AB is rotating at a constant angular velocity of 250 rpm. In all cases , express the answers using the righ-handed orthagonal component system. Determine the acceleration of the water particles that are at a distance d/2 from O (still within the horizontalportion of the pipe. Let d=9 inches.
