Water enters a hydraulic turbine through a 35-cm-diameter pipe at a rate of 0.8 m3/s and exits through a 30-cm-diameter pipe. The pressure drop in the turbine is measured by a mercury manometer to be 1.0 m. For a combined turbine– generator efficiency of 80 percent, determine the net electric power input. Disregard the effect of the kinetic energy correction factors

Storm Sewers and Detention

The storm drains system transports rainwater or stormwater and other runoff from roads, parking lots, and roof downpipes directly to nearby creeks, rivers, or the sea without any treatment.
