Match List - I with List - II :

List - IList - II
(a) Venturimeter(I) Pressure measurement
(b) Orifice meter(II) Bend at right angle
(c) Pitot tube(III) Converging diverging section
(d) Manometer(IV) Hole in a plate

Choose the most appropriate answer from the options given below :

  • A.(a)-(I), (b)-(IV), (c)-(II), (d)-(III)
  • B.(a)-(IV), (b)-(III), (c)-(II), (d)-(I)
  • C.(a)-(III), (b)-(IV), (c)-(II), (d)-(I)
  • D.(a)-(III), (b)-(II), (c)-(IV), (d)-(I)

Answer: C

The correct matching is (a)-(III), (b)-(IV), (c)-(II), (d)-(I).

  • Venturimeter: a converging-diverging section; the pressure drop at the throat measures the flow (a-III).
  • Orifice meter: a plate with a hole in it, inserted in the pipe (b-IV).
  • Pitot tube: a tube bent at right angles, its open end facing the flow, to measure velocity (c-II).
  • Manometer: a device for pressure measurement (d-I).

Only one option has the venturimeter against the converging-diverging section and the orifice meter against the hole in a plate; the option (a)-(III), (b)-(II) swaps the orifice meter and the Pitot tube.
