.Which part protects the penstock due to sudden variation of flow or velocity of water?

Question

Accepted Answer

Surge tank

A surge tank is used to protect the penstock from sudden variations in flow or velocity of water.
It absorbs the excess pressure caused by sudden changes in flow and prevents damage to the penstock.
Surge tanks are typically installed in hydropower plants and water distribution systems.
They help maintain a steady flow of water and prevent water hammer effects.
Examples of surge tanks include open surge tanks, closed surge tanks, and standpipe surge tanks.

Accepted Answer

Surge tank

For hydroelectric power uses, a surge tank is an additional storage space or reservoir fitted between the main storage reservoir and the power house (as close to the power house as possible)

In short, the surge tank mitigates pressure variations due to rapid changes in velocity of water.
