Question

there is a hole in the bottom of tank having water. if total pressure at bottom is 3 atm (1atm= 105N/m2); then the velocity of water flowing from the hole is :
a. root(400)m/s b. root(600) m/s.

Answer 1

Answer:

Correct option is

A

400m/s

Pressure at the bottom of tank P=hρg=3x105m2N

Pressure due to liquid column

P1=3x105−1x105=2x105

and velocity of water v=2gh

∴v=ρ2P1=1032x2x105=400m/s
