Textbook Problem

Blood is pumped from the heart at a rate of 5.0 L/min into the aorta (of radius 1.0 cm). Determine the speed of blood through the aorta.

To determine

The speed of blood flowing through the aorta.

Explanation

Given info:

• Blood pumping rate of heart is 5 Lmin1 .
• Converting blood flow rate in unit of cm3s-1.

5Lmin1=5 Lmin×1min60s×1000cm31L=83.33cm3s-1

• The radius of the aorta is 1cm .

Formula used:

Formula to find the average flow rate is,

Q=vA

Here, Q is the flow rate, v is the speed of the car and A is the area
