Solution suppose that a blood vessel of cross-sectional area a carries microbubbles at a speed v into a capillary bed. if the capillary bed is made up of n capillaries, each with cross-sectional area a, with what speed will the blood flow in the capillary bed

The speed of blood flow in the capillary bed is times the speed of blood flow in the blood vessel

Explanation:

Let the cross-sectional area of blood vessel be "A"

The speed of flow of blood into the capillaries is "v"

Now , it is given that capillary bed is made up of w "n" numbers of blood vessels with cross section area "A" and and speed "V"

Now as per continuity equation of flow, the flow remains constant when the density is unchanged

Thus ,

Flow in single blood vessel is equal to flow in "n" capillaries of capillary bed

Therefore,

Hence, the speed of blood flow in the capillary bed is times the speed of blood flow in the blood vessel

radon is correct hope this

correct answer: false

while planning water activities, it is very important to consider the weather, because if we do not plan and are going for a surf, then it might be that the hurricane came and drown us or may carry us to long distance from where we can not come back. there are many reasons to take information about the weather when we are planning any water activities.

hence, the correct answer would be false.
