How Hydropower Works | Wisconsin Valley Improvement Company
For the dam in our area, lets say we buy a turbine and generator with an efficiency of 80%. Then the power for our dam will be: Power = (10 feet) x (500 cubic feet per second) x (0.80) / 11.8 = 339 kilowatts. To get an idea what 339 kilowatts means, let's see how much electric energy we can make in a year.

Abutment - In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled packs behind the face.
