Question

q22. due to capillary action, a liquid will rise in a tube, if the angle of contact is
a. obtuse
b. acute
c. 90 degrees
d. 180 degrees
q23. the law is a fundamental principle in physics that describes the velocity of steady flow of a fluid through a narrow tube, such as a blood vessel or a catheter.
a. poiseuille’s law
b. bernoullis principle
c. stokes law
d. pascals law

Explanation:

Q22. When the angle of contact is acute, adhesive forces dominate and liquid rises in the tube due to capillary action.
Q23. Poiseuille’s Law relates to the velocity of steady - flow of a fluid through a narrow tube.

Answer:

Q22. B. acute
Q23. A. Poiseuille’s Law
