Fluid Dynamics

The study of the flow of gases and liquids, usually in and around solid surfaces, is known as fluid dynamics in physics and engineering. Fluid dynamics, for example, can be used to evaluate the movement of air through an airplane wing or the surface of a vehicle. It can also be used in ship design to increase the speed at which ships pass through water.

A three-arm sprinkler is used to water a garden by rotating in a horizontal plane. Water enters the sprinkler along the axis of rotation at a rate of 40 L/s and leaves the 1.2-cm-diameter nozzles in the tangential direction. The central sprinkler bearing applies a retarding torque of 50 N-m due to friction at the anticipated operating speeds. Part A For a normal distance of 40 cm between the axis of rotation and the center of the nozzles, determine the rate of rotation of the sprinkler. Express your answer to three significant figures.
