5.87 WILEY Water enters a rotating lawn sprinkler through its base at the steady rate of 60 L/min as shown in Fig. P5.87. The exit cross-sectional area of each of the two nozzles is 0.26 cm², and the flow leaving each nozzle is tangential. The radius from the axis of rotation to the centerline of each nozzle is 20 cm. (a) Determine the resisting torque required to hold the sprinkler head stationary. (b) Determine the resisting torque associated with the sprinkler ro- tating with a constant speed of 500 rev/min. (c) Determine the an- gular velocity of the sprinkler if no resisting torque is applied. |r=20 cm 11 Q = 60 L/min Figure P5.87 Nozzle exit area= 0.26 cm² 5.87 WILEY Water enters a rotating lawn sprinkler through its base at the steady rate of 60 L/min as shown in Fig. P5.87.
