4. A Pelton turbine
produces 8 MW of power
under net head of 440 m.
The turbine has two jets.
The buckets deflect the
jet by an angle of 165°. If
the bucket friction
coefficient is 0.85,
compute the following:
(a) Discharge
(b) Diameter of each jet
(c) The total force
exerted by the jets on the
wheel in the tangential
direction
(d) Power produced by
the runner
(e) Hydraulic efficiency
The overall efficiency,
coefficient of velocity and
speed ratio may be
assumed
0.85, 0.98, and 0.47,
respectively.
