Types of Flow, Reynolds Number & Continuity

An in-compressible fluid flows steadily through a horizontal cylindrical pipe. The pipe has radius '3R3R' at point A and '1.5R1.5R' at point B, further along the flow direction at the same level. If the velocity at point A is 'vv', then that at point B is

Show answer and solution

Answer: (d)

  1. Continuity: AAvA=ABvB⇒rA2v=rB2vBA_A v_A = A_B v_B \Rightarrow r_A^2 v = r_B^2 v_B
  2. vB=v(3R1.5R)2=4vv_B = v\left(\dfrac{3R}{1.5R}\right)^2 = 4v
  3. So the answer is (d) 4v4v.
