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(600)m//s`

C

`sqrt(60)m//s`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
Pressure at the bottom of tank `P= h rho g = 3 xx 10^(5)(N)/(m^2)`
and velocity of water `v = sqrt(2gh)`
`:.v=sqrt((2p)/(rho)) = sqrt((2xx3xx10^(5))/(10^(3))) = sqrt(600)m//s`.
