II. A two-armed sprinkler has four holes with diameter d in each arm as shown in the figure below. Water with density p flows at flowrate 8Q up through the central hub and then exits each of the 8 holes equally. The holes are designed such that the jets exit at a 45 angle as shown so that the sprinkler arms spin. hole diameter-d 459 A. The friction in the bearing limits the angular rotation rate. Deter- mine an expression for the resisting torque Tshaft provided by this friction if the angular rate is w.
