To identify: Whether the turbine blades are designed so that water is brought to dead stop for getting maximum power generation.
Explanation of Solution
Introduction:
Hydraulic power plants are used to produce electricity. It converts the energy of falling water into electricity.
In hydroelectric power generation, kinetic energy of the falling water is converted into mechanical energy. This mechanical energy is then converted to electric energy. If mechanical energy is large, electricity conversion will be large. If the turbine blades are designed such that water rebounds. Due to rebounding of water, change in momentum is large. This momentum is transferred to the turbine blades due to which power generation increases.
Conclusion:
The turbine blades are designed such that momentum of water is transferred to the turbine.
