Venturimeters, orificemeters and nozzles are used to measure the fluid discharge from a pipeline. The average fluid velocity in a pipeline can be measured by a/an________________?
Correct answer: B. Hot wire anemometer
- A. Weir
- B. Hot wire anemometer
- C. Cup and vane anemometer
- D. None of these
Explanation
A hot-wire anemometer determines fluid velocity from the cooling effect of the flowing fluid on a heated wire, and it can be used to obtain the average velocity by suitable measurement across the pipe. Weirs measure open-channel discharge, while cup-and-vane anemometers are mainly used for air movement.
