Answer -
Answer: (a)
Take the case given in figure (b).
Where,
A1 =Area of pipe1
A2 =Area of pipe 2
V1 =Speed of the fluid in pipe1
V2 =Speed of the fluid in pipe 2
From the law of continuity, we have:
When the area of cross-section in the middle of the venturimeteris small, the speed of the flow of liquid through this part is more. Accordingto Bernoulli’s principle, if speed is more, then pressure is less.
Pressure is directly proportional to height. Hence, the level ofwater in pipe 2 is less.
Therefore, figure (a) is not possible.
