This
investigation was carried out to evaluate the characteristics of a Francis
water turbine. Several variations of inlet valve openings of the turbine were
tested to determine the effects of changes in rotational speed of runner on
turbine performance. The method used in this study was experimental measurement
using a test rig installation in Diponegoro University. The results found that
discharge was not change significantly with increasing speed. The torque
decreases as the turbine rotational speed increases. The break horse power
(BHP) and efficiency curves are nearly identical. Both BHP and efficiency
increase when speed are increased until the maximum condition is reached, then
from this maximum condition, as speed increase, the BHP and efficiency gradually
decrease.
