Kaplan turbines are used whenever the water head is

Kaplan turbines are used whenever the water head is Correct Answer low

The correct option is low.

Concept:

Kaplan turbines

  •  It uses lower head sites with high flow rates(100m).
  • High specific speed (250-100 rpm)
  • It uses impeller buckets and 4-8 vanes.
  • It has very large flow rate.

 

Pelton turbines

  • It uses very high head sites with high flow rates(300-400m).
  • Low specific speed.
  • It uses wheel with 20-40 buclets.
  • It has low flow rate.

 

Hence, the correct answer is Kaplan turbines uses low water head.
