[QUOTE="brambedkar59, post: 1039770, member: 61084"] That figure "92%" has to be the hydraulic efficiency and not the overall efficiency. Also, there are 4 reasons for splitting the water jet into two parts: [LIST=1] [*]More efficiency (getting more energy out of incoming water jet, you would have to draw momentum vector diagram for that to understand). [*]Less damage to turbine because of cavitation. [*]Increase in Lateral stability of turbine. [*]Doesn't hit the next turbine bucket, thus preventing energy loss. [/LIST] 3:17 That's scary to look at. [MEDIA=youtube]DbvgK3PrSWw[/MEDIA] [/QUOTE]
