A hole is made at the bottom of the tank...

A hole is made at the bottom of the tank filled with water (density `=1000 kgm^(-3))`. If the total pressure at the bottom of the tank is three atmospheres (1 atmosphere `=10^(5) Nm^(-2))`, then the velocity of efflux is nearest to

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 = 3 atm - 1 atm = 2 atm = 20 m of water column height of the weight the tank is h = 20 m Velocity of efflux `=sqrt(2gh)=sqrt(2xx10xx20)=sqrt(400)m//sec`
