DAM DEDUCTION 1|li'ilater exiting a hydropower dam is called non-powered or powered outflow. Non-powered outflow exits via a spillway, on top of the darn. Powered outflow, which is used to generate electricity, travels through penstocks, pipes at the bottom of a dam. Powered outflow is usually colder and travels at a higher velocity, so it can disturb sediments, temperatures, and water quality of downstream rivers, especially when it's a high percentage of the total outflow. The SWOT mission, a satellite designed to survey all of Earth's surface water, including lakes, rivers, oceans, and reservoirs, can help scientists better analyze these impacts. A dam has 3 penstocks with diameters of 6.2 meters and a measured total outflow of 1,350 mafs. If SWOT measured the reservoir's water depth {H} at 100 m above the penstoclas, compute the velocity {mfs} of the powered outflow using V = 1' 2gH . What is the powered outflow if'l penstock is open? Is this a high or low percentage of the total outflow? What can this tell you about the potential environmental impacts? LEARN MORE swot.jpl.nasa.gov
