Web, where P =generator output (power) in kilowatts (kW), e =overall plant efficiency, H=head (foot [ft] or meter [m] depending on which equation is used), and Q=flow (cubic feet or cubic meters per second depending on which equation is used. This equation assumes a constant water density of 62.4 lb/ft 3 or 9806 N/m 3. View chapter Purchase book WebOver time, water vapor in the atmosphere condenses into clouds and eventually falls as precipitation, rain or snow. When precipitation reaches Earth's surface, it has a few options: it may evaporate again, flow over the surface, infiltrate into the soil, or percolate —sink …
