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.
