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.

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
