2016-17 Q3 PHYS123 k Problem 18.27 Problem 18.27 (Figure 1) shows streamlines of water flowing in two regions A and B of the same pipe (neither of the two regions shown spans the entire diameter of the pipe). Between these two regions no other pipes are connected to this one. Figure 1 1 session.masteringphysics.com Part A Compare the speed in the two regions A and B. O The flow speed in regions A and B is the same.

(A) The flow speed in region B will be greater then A as here area is less and water will flow in same amount in same time for this speed should be greater
So option B is correct
(B) As speed in region B is greater so pressure would be less
Option C is correct
(C) Area of region B is smaller
Option B is correct
