Correct Bernoulli's equation is (symbols have their usual meaning) : (1) P + mgh + 1/2 mv^2 = constant

Question

Correct Bernoulli's equation is (symbols have their usual meaning) :

(1) \(\mathrm{P}+\mathrm{mgh}+\frac{1}{2} \mathrm{mv}^{2}=\) constant

(2) \(P+\rho g h+\frac{1}{2} \rho v^{2}=\) constant

(3) \( \mathrm{P}+\rho g h+\rho v^{2}=\) constant

(4) \( P+\frac{1}{2} \rho g h+\frac{1}{2} \rho v^{2}=\) constant

Answer 1

Correct option is : (2) \( P+\rho g h+\frac{1}{2} \rho v^{2}=\) constant 

Energy per unit volume is conserved.
