Answer to Question #233528 in Quantum Mechanics for NoobEngineer

Question

A Pelton wheel of 1.2 m mean bucket diameter works under a head of 650 m. The jet deflectionis 1650 and its relative velocity is reduced over the buckets by 15% due to friction. If the water isto leave the bucket without whirl, determine the rotational speed of the wheel. The coefficient ofvelocity is C, 50.98(a) 786.38 rpm(b) 1425.36 rpm(c) 320.2 rpm(d) 480.6 rpm
In the above problem, the ratio of bucket to jet speed can be calculated as(a) 0.1(b) 1.5(c) 0.45(d) 2.52
In the above problem, for a jet diameter of 100 cm, the impulsive force on a bucket of the Peltonwheel can be calculated as(a) 12.26 kN(b)62.36 kN(c) 32.36 kN(d) 94.26 kN
