A small Pelton wheel is used to power an oscillating lawn sprinkler as shown in Fig. P12.50. The arithmetic mean radius of the turbine is \(1 \mathrm{in}\)., and the exit angle of the blade is \(135^{\circ}\) relative to the blade motion. Water is supplied through a single 0.20 -in.-diameter nozzle at a speed of \(50 \mathrm{ft} / \mathrm{s}\). Determine the flowrate, the maximum torque developed, and the maximum power developed by this turbine.
