Apelton wheel operates from a net head of h 300 m and at a flow rate of 4.2 m /s. the wheel diameter is 1.5 m. and the rotational speed is 450 rpm. the water that leaves the penstock is divided into 5 streams. the nozzle coefficient is cn 0.98 for each nozzle. impulse blades turn the flow into the direction b2 25, and as a result of friction, the relative velocity reduces by an amount that gives a velocity coefficient cy 0.90. find (a) work output of the turbine, (b) the hydraulic efficiency, (c) the nozzle diameter and the number of buckets in the wheel.
