The velocity of water flow (density 1000 kg/m3) in a horizontal pipe is measured using the PITOT tube shown below. The fluid in the U-tube manometer is mercury with a density of 13534 kg/m3. Assume g = 9.81 m/s2. If the height difference (h) is measured as 94.1 mm, the velocity of flow of water in m/s is
  • a)
    4.81 m/s
  • b)
    9.62 m/s
  • c)
    7.21 m/s
  • d)
    3.62 m/s
Correct answer is option 'A'. Can you explain this answer?

The velocity of flow of water
V = √2gh
h = (Sm / S) - 1 = 94.1 x 10-3 x {(13534/1000) - 1}
h = 1.18 m
Putting values, we get
V = 4.81m/sec
