Owing to a sudden closure of turbines in a powerhouse:
  • a)
    A positive surge will occur in head race channel with surge front moving downstream
  • b)
    A positive surge will occur in head race channel with surge front moving upstream
  • c)
    A negative surge will occur in head race channel with surge front moving up stream
  • d)
    A negative surge will occur In head race channel with surge front moving downstream
Correct answer is option 'B'. Can you explain this answer?

If the sluice gate of the head race channel is suddenly closed (for closing turbine) positive surge will move upstream. If the sluice gate is suddenly opened (to start turbine) positive surge will move downstream.

Explanation:

Sudden Closure of Turbines:
- When turbines in a powerhouse are suddenly closed, it causes a rapid decrease in flow and pressure within the system.
- This sudden closure can result in a surge or water hammer effect in the head race channel.

Positive Surge in Head Race Channel:
- Due to the sudden closure of turbines, a positive surge will occur in the head race channel.
- This surge is characterized by an increase in water level and pressure within the channel.

Surge Front Direction:
- The surge front, which is the leading edge of the surge wave, will move upstream in the head race channel.
- This means that the surge front will move in the opposite direction to the normal flow of water within the channel.

Effects of Positive Surge:
- The positive surge moving upstream can cause water levels to rise rapidly, potentially leading to overflow or damage to the channel walls.
- It can also result in increased pressure within the system, which may impact the overall stability and functioning of the powerhouse.
Therefore, owing to a sudden closure of turbines in a powerhouse, a positive surge will occur in the head race channel with the surge front moving upstream.
