Flow rate of a river is measured by a/an____________________?
Correct answer: B. Vane meter
- A. Pitot tube
- B. Vane meter
- C. Kennison nozzle
- D. Open weir
Explanation
A vane meter, or current meter, measures the local velocity of flowing river water; discharge is then obtained from velocity measurements over the river cross-section. An open weir requires a constructed control structure and is more typical of canals or small channels.
