A rection turbine has guide
vane angle 30° the runner
blades make an angle of 80°
relative to the tanget at
inlet .the blades width at
inlet is 1/4 of the outer
diameter .the water does
not have any tanget velocity
at outlet.the head is 25 m
and the rotational speed of
the runner is 16.67 rotation
per second (rps) the turbine
efficiency is 88%
determine the runner
diameter at the inlet and the
power developed by this
turbine
