There is a small hole at the bottom of tank filled with water. If total pressure at the bottom is `3 atm(1 atm=10^(5)Nm^(-2))`, then find the velocity of water flowing from hole.

A

`sqrt(400) m//s`

B

`sqrt(200) m//s`

C

`sqrt(600) m//s`

D

`sqrt(500) m//s`

Text Solution

Verified by Experts

The correct Answer is:
A
Pressure due to water in the tank `=3atm-1atm=2atm=20m` of water column height of the water in the tank is `h=20m` velocity of efflux`=sqrt(2gh)=sqrt(2xx10xx20)=sqrt(400)m//sec`
