The appropriate value of the estimated average life of a dam reservoirs is
Answers
Answer:
Explanation:
Life-span of dams and components
The service life of a well-designed, well-constructed and well-maintained and monitored embankment and concrete dams can easily reach 100 years. Hydromechanical elements such as gates and their motors have to be replaced after 30 to 50 years.
A dam is a hydraulic structure constructed across a river in order to store water on its upstream side or divert water from the river.
The service life of a well-designed, well-constructed, and well-maintained and monitored embankment and concrete dams can easily reach 100 years.
But the appropriate value of the estimated average life (in years) of a dam reservoir is taken as 75 years.
The life-span of penstocks is 40 to 60 years
The service life of hydromechanical elements such as gates and their motors have to be replaced after 30 to 50 years.
The service life of electro-mechanical equipment varies from 20 to 60 years
