Q. Which of the following is true in case of flow of water before it enters the runner of a Francis Turbine?

  • (A) available head is entirely converted to velocity head
  • (B) available head is entire converted to pressure head
  • (C) available head is neither converted to pressure head nor velocity head
  • (D) available head is partly converted to pressure head and partly to velocity head

✅ Correct Answer: (D) available head is partly converted to pressure head and partly to velocity head
Explanation: since francis turbine is a reaction turbine, part of the available head is converted to velocity head. it is not entirely converted to velocity head. the rest of the available head is converted into pressure head.
