Question

The number of buckets required to maintain optimum efficiency of a Pelton turbine is usually
fixed by the empirical relation: number of buckets =
ratio), where Jet ratio is the
ratio of the mean bucket diameter or pitch diameter to the nozzle diameter. With this information
answer the following problem-
For the standard design of a desired Pelton wheel, it is observed that if the jet ratio is increased
by five times, then the number of buckets on the runner has to be doubled. If the diameter of the
jet is 0.15 m, then the pitch diameter of the desired Pelton wheel is:
(a) 0.3
(b) 3m
(c) 0.75m
(d) 1.5m

​

Answer 1

Answer:

this answer is 3m

this answer is 3 m
