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.
