Poiseuille's Law states that the volume, V, of blood flowing through an artery in a unit of time at a fixed pressure is directly proportional to the fourth power of the radius of the a That is, V = kr“, where r is the radius of the artery. If the radius is increased by about 4 %, by about how much will the volume of blood flowing through the artery increase? 16 % By about how much must the radius of the artery be increased to achieve a 50 % increase in the volume of blood flowing through the artery?| % Note: enter an answer accurate to 4 decimal places.
