Water flowing through a cylindrical pipe suddenly comes to a section of pipe where the diameter decreases to 86% of its previous value. If the speed of the water in the larger section of the pipe was what is its speed in this smaller section if the water behaves like an ideal incompressible fluid?

What if it's 44 m/s?

Using continuity equation A1V1 = A2V2

A = π(D/2)2

π(D/2)2 x 44 = π(0.86D/2)2 x v'

v' = 59.49 m/s
