Question

The efflux velocity of a liquid of density $1500kg{m}^{-3}$ from a tank in which the pressure of liquid is $1000pa$ above the atmosphere is :

• A. $115m{s}^{-1}$
• B. $11.5m{s}^{-1}$
• C. $0.115m{s}^{-1}$
• D. $1.15m{s}^{-1}$

Answer 1

The correct option is D $1.15m{s}^{-1}$

The velocity of a liquid is given as,

$v=\sqrt{2gh}$

$v=\sqrt{2g\times \frac{\Delta P}{\rho g}}$

$v=\sqrt{2\times \frac{1000}{1500}}$

$v=1.15m/s$
