Imagine that you have been employed as a consultant to design a single-jet pelton wheel that is 90% efficient with a jet velocity of vj=90 m/s. you must use a motor that runs with a torque of = 107 n. m. the jet is driven by a water reservoir at 20ºc with a head hp=325 m. now, imagine that you arrive at a design with a specific speed of ns= 0.11. determine the angular velocity (), the volumetric flow rate (q), and the radius of the wheel (r). assume ηt= 0.92 and λ = 0.5. the output torque is related to the jet velocity and the wheel radius by the expression: 2   j   qr v 
