In the diagram shown, the difference in the two tubes of the manometer is 5cm, the cross section of the tube at A and B is 6mm2 and 10mm2 respectively. The rate at which water flows through the tube is (g=10ms−2)





A

7.5cc/s

B

8.0cc/s

C

10.0cc/s

D

12.5cc/s

Correct option is

A

7.5cc/s

Let the velocities at the ends A and B be v1 and v2

Using, equation of continuity 6v1=10v2

⇒v1=35v2

Now, using Bernoulli's equation:

P1+21ρv12=P2+21ρv2
