f utilising the energy ofelevated water is by the employment of turbines. In these machinesthe water passes through a wheel furnished with blades. The actionconsists in causing the water to whirl before entering the wheel ; intins condition it possesses angular momentum, and the function ofthe… … Fig. 315.—Over-shot water-wheel. XXI WATER TURBINES 293 In impulse turbines arrangements are made so as to convert thewhole of the available energy of the water into the kinetic formbefore it enters the wheel. In reaction turbines the energy is partlyin the kinetic form and partly in the form of…
