The velocity of the liquid coming out of...

The velocity of the liquid coming out of a small hole of a vessel containing two different liquids of densities `2rho` and `rho` as shown in the figure is

A

` sqrt (6 gh ) `

B

` 2sqrt (gh)`

C

` 2 sqrt (2 gh ) `

D

` sqrt (gh ) `

Text Solution

Verified by Experts

The correct Answer is:
B
Applying Bernoulli between points just inside and outside the hole :
` P_0 + rho g (2h ) + 2 rho gh = P _ 0 + (1)/(2) 2 rho v ^2 `
` v = 2 sqrt (gh) `
