A fluid of density \(\rho~\)is flowing in a pipe of varying cross-sectional area as shown in the figure. Bernoulli's equation for the motion becomes:
1. \(p+\dfrac12\rho v^2+\rho gh\text{=constant}\)
2. \(p+\dfrac12\rho v^2\text{=constant}\)
3. \(\dfrac12\rho v^2+\rho gh\text{=constant}\)
4. \(p+\rho gh\text{=constant}\)

NEET MCQ Books for XIth & XIIth Physics, Chemistry & BiologyWater is flowing through a long horizontal tube. Let \(P_A\) and \(P_B\) be the pressures at two points \(A\) and \(B\) of the tube.
1. | \(P_A\) must be equal to \(P_B\). |
2. | \(P_A\) must be greater than \(P_B\). |
3. | \(P_A\) must be smaller than \(P_B\). |
4. | \(P_A\) = \(P_B\) only if the cross-sectional area at A and B are equal. |
