Abstract
The installed capacity of hydro-electric plants has been increasing almost continuously since 1900. Concurrently, the maximum size and horse-power of individual units have grown by leaps and bounds. The limit in efficiency was closely approached by 1920, and the most important event in the history of turbine design since that time is the development of the propeller-type turbine.
This paper reviews briefly the important design features of modern high-head, medium-head, and low-head turbines; discusses the importance of laboratory testing (with special reference to low-head installations); points to six important mechanical improvements in turbine design made since about 1925; and concludes with an examination of possible future developments, such as the pumped-storage plant and the use of the propeller-type turbine for higher heads.
