At a hydroelectric power plant, water is directed at high speed against turbine blades on an axle that turns an electric generatior. For maximum power generation, should the turbine blades be desigened so that the water is brought to a dead stop, or so that the water rebounds?

In a hydroelectric power plant more electrical power can be generated if water falls a greater height because :

In Koyna hydroelectric power station, water stored at a height of 600 metre fall on the turbine blades and the water flow avilable is 100 m^(3)//s . The efficiency of the turbine generator is 50%. What is the power available from the power station? [g=10 m//s^(2)]

Dams store water for irrigation, home use, and hydroelectric power. Why should the dams be constructed so that they are much thicker at the bottom than at the top ?

At a hydroelectric power plant, the water pressure head is at a height of 300 m and the water flow available is 100 m^(3) s^(-1) . If the turbine generator efficiency is 60%, estimate the electric power available from the plant (g = 9.8 ms^(-2)) .

Water falls from a height of 60m at the rate of 15 kg/s to operate a turbine. The losses due to frictional force are 10% of the input energy. How much power is generated by the turbine?

In generation of hydroelectric power, water falls from some height and gravitational potential energy of water is converted into electric power with the help of turbine. In one such event, 7.2xx10^4kg of water falls per hour from height 100m and half of the gravitational potential energy is converted into electric energy. How much power is generated?
