Consider an impulse turbine with a pitch diameter of 2.0 m and a bucket angle β₂ of 165°. If the jet velocity is 86 m/s, the jet diameter 108 mm, and the rotative speed 375 rpm, find (a) the force on the buckets, (b) the torque on the runner, and (c) the horsepower transferred to the runner. Assume that the velocity relative to the bucket does not change (i.e. assume v₂ = v₁).
