• A. A B C D
  2 3 4 1
• B. A B C D
  5 2 3 4
• C. A B C D
  2 5 1 3
• D. A B C D
  5 2 3 1

Answer 1

The correct option is D A B C D

5 2 3 1

(d)

The constant temperature hot-wire anemometer may be conveniently used for velocity measurement even when the velocity fluctuations are large. Thus they can measure turbulence also.
