Inscription. Imagine this 125-ton carbon-steel turbine spinning at 81.8 revolutions per minute. Picture more than 99.491 gallons of water per second rushing through the intake to spin its heavy blades, which generate 36 megawatts of electricity. Measuring over 24 feet wide and nearly 13 feet tall, this Kaplan adjustable-blade turbine, the fourth to be installed at Pickwick Dam, began commercial operation in 1942. Although it's huge, this turbine plays only a small role in TVA's balanced river system. Hydroelectirc Dam

Also see . . . Kaplan turbine. The Kaplan turbine was an evolution of the Francis turbine. Its invention allowed efficient power production in low-head applications that was not possible with Francis turbines. The head ranges from 10–70 metres and the output from 5 to 200 MW. Runner diameters are between 2 and 11 metres. Turbines rotate at a constant rate, which varies from facility to facility. That rate ranges from as low as 69.2 rpm (Bonneville North Powerhouse, Washington U.S.) to 429 rpm. The Kaplan turbine installation believed to generate the most power from its nominal head of 34.65 m is as of 2013 the Tocoma Dam Power Plant (Venezuela) Kaplan turbine generating 230 MW (Turbine capacity, 257MVA for generator) with each of ten 8.6 m diameter runners.
