A large tank with a nozzle attached contains three immiscible, inviscid fluids as shown. Assuming that the changes in h₁, h₂ and h₃ are negligible, the instantaneous discharge velocity is

2. √2g(h₁ + h₂ + h₃)

Correct Option: A

Applying Bernoulli’s equation at exit, we get

P₁	+ gz₁ +	V₁²	=	P₁	+ gz₂ +	V₂²
ρ₃	+ gz₁ +	2	=	ρ₃	+ gz₂ +	2

We know Z₁ = Z₂, V₁ = 0 & P₂ = P_atm
Hence it reduce to

P₁	=	V₂²
ρ₃	=	2
