For the average speed of blood flow in the major arteries of the body  is mathematically given as

v2 = 117.29m/s

What is the average speed of blood flow in the major arteries of the body?

Generally, the equation for the average speed  is mathematically given as

A1 v1 = A2 v2

(pi r1^2) v1 = A2 v2

(3.14x(1.4)^2 )x 40 = (2.1) xV2

v2 = 117.29m/s

In conclusion, the average speed of blood flow

v2 = 117.29m/s
