The top of a water tank is open to air and its water lavel is maintained. It is giving out `0.74 m^(3)` water per minute through a circular opening of 2 cm radius in its wall. The depth of the centre of the opening from the level of water in the tank is close to :

A

9.6 m

B

4.8m

C

6.0 m

D

2.9 m

Text Solution

Verified by Experts

The correct Answer is:
B
`Q=AV`
`((0.74)/(60))=pixx4xx10^(-4)sqrt(2gh)~~4.8m`
