In case of a pipe exit fitted with a nozzle, the____________________?
Correct answer: E. Both B. and C.
- A. Conversion of kinetic head to pressure head is facilitated
- B. Conversion of pressure head to kinetic head is facilitated
- C. Power transmitted through the nozzle is maximum, when the head lost due to friction in the
- D. pipe is equal to one third of the total supply head
- E. Both B. and C.
Explanation
A nozzle converts pressure head into velocity head, so it increases the exit velocity. Since nozzle power is proportional to flow rate times nozzle head, maximum power occurs when pipe-friction loss is one-third of the supply head, making both statements valid.
