Answer to Question 1

ANS: C
During laminar flow, a fluid moves in discrete cylindrical layers or streamlines.

Answer to Question 2

ANS: C
For any given tube length, flow resistance equals the difference in pressure between the two points along the tube divided by the actual flow. This is expressed as a formula:
R = (P1  P2)  V
