Water flows steadily through a horizontal pipe of a variable cross-section. If the pressure of water is P at a point where the velocity of flow is v, what is the pressure at another point where the velocity of flow is 2v; ρ being the density of water ?
- \(P-\frac{3}{2} \rho v^{2}\)
- \(P+\frac{3}{2} \rho v^{2}\)
- P – 2ρv2
- P + 2ρv2
Answer
(A) P- 3 2 v^ 2
