An incompressible fluid flows steadily through a cylindrical pipe having radius R at point A and (R/3) at point B further along the direction of flow of liquid. If the velocity at point A is ' V ' then that at point B is (a) V/9 (b) V/3 (c) 3 V (d) 9 V

Answer: (d). Continuity: π R² V = π (R/3)² vB vB = 9V So the answer is (d) 9V.

Types of Flow, Reynolds Number & Continuity

An incompressible fluid flows steadily through a cylindrical pipe having radius R at point A and $\left(\frac{R}{3}\right)$ at point B further along the direction of flow of liquid. If the velocity at point A is ' V ' then that at point B is

Show answer and solution

Answer: (d)

Continuity: $\pi R^2 V = \pi (R/3)^2 v_B$
$v_B = 9V$
So the answer is (d) $9V$ .
