Air Demand Tests, Libby Dam, Kootenai River, Montana
Tests were conducted to determine the quantity of air drawn into one of the Libby Dam sluices following installation of a special aerator device. The test program measured air demand drawn into the test sluice through a full range of gate openings at 1-ft increments from 1 through 16-ft with essentially full pool (2447.7 ft msl). Data reduction indicated that most of the air is drawn into the aerator through the air vent and the equipment shaft (when open). At most gate openings the airflow rate was not constant, experiencing sudden gusts of high velocity. The largest recorded air vent flow occurred between gate openings of 7 to 12 ft (40 to 70 percent). (Author)
