Francis turbine Units 19, 20, and 21, installed at the Grand Coulee Dam
Â
Francis turbine Units 19, 20, and 21, installed at the Grand Coulee Dam on the Columbia River, are very large [46]. Each runner is 32.6 ft in diameter and contains] 550 tons of cast steel. At rated conditions, each turbine develops 820,000 hp at 72 rpm under 285 ft of head. Efficiency is nearly 95 percent at rated conditions. Thel turbines operate at heads from 220 to 355 ft. Calculate the specific speed at rated operating conditions. Estimate the maximum water flow rate through each turbine.!
