## Homework Statement

## Homework Equations

Bernoulli's equation : ##P + \frac{1}{2}ρv^2 + ρgh ## = constant

## The Attempt at a Solution

The pressure at the interface is ##P_{int} = P_0 + ρgH## .

Applying bernoulli's equation between point at the interface of two liquids and exit of the tube .

##P_{int} + ρg(\frac{H}{2}+\frac{H}{4}) ## = ## P_0 + \frac{1}{2}(2ρ)v^2##

##v = \frac{\sqrt{7gH}}{2}## .

This doesn't give correct answer .

.What is the mistake ?

Thanks
