Assuming a constant flow, what will happen to a fluid if the cross-sectional area of the tube in which its flows decrease?

Question

Quizplus · Accepted Answer

Throughout the tube, the fluid flows at a constant rate of 5 L/min. At point A, with a cross-sectional area of 5.08 cm², the velocity of the fluid is 16.4 cm/sec. At point B, the cross-sectional area of the tube decreases to 2.54 cm², half its prior value. At this point, the velocity of the fluid doubles to 32.8 cm/sec.
