Difference between Francis turbine and Kaplan turbine
	Francis turbine	Kaplan turbine
1.	It needs one servomotor be regulation of direct vanes.	It requires servomotors for regulation of vanes with turning runner blades.
2.	Shaft might be placed horizontally and vertically.	Shaft of runner is for all time vertical.
3.	Precise speed range as of 50 to 250.	Precise speed ranges as of 250 to 850.
4.	Servomotor is located outside rotor shaft.	Servomotors are located inside hollow shaft of turbine runner.
5.	Flow of water is radially and mixed flow type.	It is simply axial flow turbine.
6.	Number of vanes is big (16 to 24 blades).	Number of vanes is little (3 to 8 blades).
7.	Runner vanes is not regulating.	Runner vanes are regulating.
8.	Turbine works by middle discharge at average head.	It works by high discharge by low heads.
