When the water is suddenly released in penstocks, there may be a problem of water hammer. To avoid this, surge tanks are employed, which decrease the pressure of water, thereby preventing water hammer.

Understanding Surge Tanks
Surge tanks are essential components in hydraulic systems, particularly in hydropower plants. Their primary function relates to managing pressure fluctuations.
Function of Surge Tanks
- Pressure Regulation: Surge tanks act as a buffer to absorb sudden changes in water pressure that can occur due to rapid changes in flow, such as the abrupt closure of a valve.
- Water Hammer Prevention: When there is a sudden stop in water flow, a phenomenon known as water hammer can occur, leading to shock waves that may damage pipes and equipment. Surge tanks help mitigate these shock waves by providing a space for excess water to expand and absorb energy.
- Stability in Operation: By maintaining a more stable pressure within the system, surge tanks ensure that turbines operate smoothly without experiencing damaging fluctuations.
Additional Functions
- Storage Capability: While surge tanks do provide some storage, this is not their primary function. They are designed more for immediate pressure management rather than long-term water storage.
- Collecting Water Post-Turbine: After the water has passed through the turbine, surge tanks can collect it, but this is secondary to their role in pressure regulation.
Conclusion
In summary, the main function of surge tanks is to prevent water hammer problems (option 'B'). By absorbing pressure surges, they protect the integrity of the hydraulic system, ensuring safe and efficient operation of turbines and other equipment in hydropower plants.
