Glycerin at room temperature is made to flow through a pipe
(the ID is 1.2 mm) at a Reynolds number of 1.00 × 102. What is the
average velocity of the glycerin? What is the average velocity if the fluid is
water instead? Which flow generates more friction? Be quantitative in your
answer and explain.
