In the generation of hydroelectric power, water is collected or stored at a higher elevation and led downward through large pipes or tunnels (penstocks) to a lower elevation; the difference in these two elevations is known as the head.At the end of its passage down the pipes, the falling water causes turbines to rotate. The turbines in turn drive generators, which convert
