Question

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(600)m//s`
D. None of these

Answer 1

Correct Answer - B
Pressure at the bottem of tank `P=hrhog=3xx10^(5)(N)/(m^(2))` and velocity of water
`v=sqrt(2gh)`
`therefore v=sqrt((2P)/(rho))=sqrt((2xx3xx10^(5))/(10^(3)))=sqrt(600)m//s`
