WebOct 28, 2024 · Large dams are vital for large-scale hydropower, but dams of all sizes are also used for flood control, water storage and irrigation throughout the world. Gates on the dam open, and gravity pulls the intake water through the penstock, a pipeline that leads to the turbine. Water builds up pressure as it flows through this pipe. WebAug 12, 2024 · Hydroelectric dams work by "reserving" a river's water and potential energy. The hydraulic head, created by the depth of the water and the water's velocity as it travels through the dam's penstock, enables the turbine in the hydroelectric plant to spin. Step 2: Turning the hydroelectric turbine Mechanical fans vary in shape and size. WebSince its completion, Hoover Dam has wowed visitors with its sheer massiveness and its ability to create and hold back a reservoir that covers nearly 650 square kilometers (250 square miles).
