Question

In the study with rat tissues, fluid flows at a speed of 0.30 mm/s through a typical capillary opening caused by a burst microbubble. Given this, which of the following is closest to the volume flow rate of fluid passing through the opening?

a. 0.0015 mm^3/s
b. 0.075 mm^3/s
c. 0.15 mm^3/s
d. 0.30 mm^3/s

Answer 1

The volume flow rate of fluid through a capillary opening caused by a burst microbubble cannot be determined without the radius or diameter of the capillary opening. The fluid flow speed alone is insufficient to calculate the volume flow rate.

Step-by-step explanation:

The student's question pertains to the volume flow rate of fluid passing through a capillary opening due to a burst microbubble. The speed of the fluid flow is given as 0.30 mm/s. To find the volume flow rate (Q), the area (A) of the capillary opening must be known. Assuming the opening is circular, the area can be found using the formula A = πr^2, where r is the radius of the capillary. However, without the radius or diameter of the capillary, we cannot calculate the exact area and thus cannot find the volume flow rate explicitly. So, the correct answer cannot be determined from the given question since essential data is missing.
