An ordinary garden hose sprinkler is sketched in Fig. 7.39. All the fluid enters at the axis (r ≈ 0) and leaves through the nozzles (r = 6 in). If the total flow rate is 5 gal / min, and the rotor is held in place by someone's hand, how much torque will the rotor exert? The jets leaving the sprinkler each have a diameter of 0.25 in.
