Question

If the aorta (diameter of da) branches into two equal-sized arteries with a combined area equal to the aorta, what is the diameter of one of the branches?

Answer 1

If each of the branches has half the area of the aorta, its linear scale factor is the square root of 1/2, or (√2)/2.

The diameter of one of the branches is (da×√2)/2.
