Hydraulic Turbine Contra-Angle Handpiece

The Journal of the American Dental Association, 1953
A high rotary speed enhances the effi­ ciency of instruments used for cutting teeth in operative procedures. The small diameters of the dental cutting tools make it necessary to turn the instru­ ments at high rates of speed in order to obtain effective linear speeds for the re­ moval of enamel.

Practical hydraulic turbine model

2006 IEEE Power Engineering Society General Meeting, 2006
This paper reports on some practical hydraulic turbine models for Francis turbines and pumped-storage hydraulic turbines. The power system frequency during transient conditions greatly depends on governor control characteristics. Hydraulic governors take on an important role to stabilize a power system frequency.

Hydraulic turbine efficiency

Canadian Journal of Civil Engineering, 2001
A set of empirical equations has been developed which defines the peak efficiency and shape of the efficiency curve for hydraulic turbines as a function of the commissioning date for the unit, rated head, rated flow, runner speed, and runner throat or impulse turbine jet diameter.
