The Flow of Blood Through an Arteriole in Cubic Centimeters

question 36

Multiple Choice

The flow of blood through an arteriole in cubic centimeters per second is given by ​ ​
Where l is the length (in cm) of the arteriole, r is its radius (in cm) , p is the difference in pressure between the two ends of the arteriole (in dyne/cm2) , and k is the viscosity of blood (in dyne-sec/cm2) . Find the approximate percentage change in the flow of blood if an error of 4% is made in measuring the length of the arteriole and an error of 3% is made in measuring its radius. Assume that p and k are constant.
