Kaplan water turbine is commonly used when the flow through its runner is (A) axial and the head available is more than 100 m (B) axial and the head available is less than 10 m (C) radial and the head available is more than 100 m (D) mixed and the head available is about 50 m

1. (A)
2. (B)
3. (C)
4. (D)

Correct answer: (B)

Solution

The Kaplan turbine is designed for low-head applications, typically under 10 meters, where the flow is axial, making it suitable for efficient operation in such conditions.
