In the human body, blood vessels can dilate, or increase their radii, in response to various stimuli, so that the volume flow rate of the blood increases. Assuming that the pressure at either end of a blood vessel, the length of the vessel, and the viscosity of the blood remain the same, determine the factor Rdilated/Rnormal by which the radius of a vessel must change in order to double the volume flow rate of the blood through the vessel.

00:01 So in answering this question, we're going to be dealing with a q2 to q1 ratio that represents the volumetric flow rates.
00:08 And this ratio is equal to 2.
00:11 Recall that the value of q is determined from delta p over 8l multiplied by the value of pi r raised to the power of 4.
00:22 So if we look at this term right here, this is of constant, meaning we are looking at r2 raised to the power of 4, 2 r1 raised to the power of 4 as being equal to 2...
