## The Attempt at a Solution

I don't understand which concept to apply in this question . The hint says to apply Bernoulli's equation and uses ∆P (excess pressure ) = (1/2) ρ v

^{2}. This does give right answer .

But I think this is wrong . We cannot apply Bernoulli's equation as it will not be a steady flow .

What is the relevant principle to be applied in this problem ?
