Calculate the average speed of blood flow in the major arteries of the body which"

Answer:
Explanation:
The aorta = narrow = I will use the subscript n to represent variables related to the aorta
The artery = wide = I will use the subscript w to represent variables related to the aorta
We use the flow rate equation:
A1 * V1 = A2 * V2 --> and now we relate it to the question --> An * Vn = Aw * Vw
A is area, and V is velocity
I first need to find the area of the aorta, as it only gives me 1.3 cm as a radius.
Convert 1.3 cm to m by dividing by 100 --> 1.3cm / 100 = 0.013m
Assuming the aorta is circular, we can find the area as (pi)r^2:
(pi)*(0.013m)^2 = approx. 5.309e-4m^2
To keep the units alike, I will now convert the area of the artery (2.2cm^2) to m^2:
2.2cm^2 = 2.2e-4m^2
Converting the velocity of blood in aorta from 40 cm/s to m/s --> 0.4 m/s
Now we plug the numbers in:
An * Vn = Aw * Vw
(5.309e-4 m^2) * (0.4 m/s) = (2.2e-4 m^2) * Vw
2.1236e-4 m^3/s = (2.2e-4 m^2) * Vw
Vw = approx. 0.96527 m/s
The velocity of blood flow in the major arteries of the body is approximately 0.96527 m/s or 96.527 cm/s
