3.43 Turbines convert the energy contained within a fluid into mechanical energy or shaft work. Turbines are often used in power plants with generators to produce electricity. One such installation is in a dam as shown in Figure P3.43. Water is permitted to flow through a passageway to the turbine, after which the water drains downstream. For the data given in Figure P3.43, determine the power available to the turbine when the discharge at the outlet is 30 m³/s. FIGURE P3.43 |V1 Water 20 m 6 m 2.7 m

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.
