Well, basically, we can increase the radius by factor of 1.5, and that's equivalent to only increasing the radius by 50%. And that's because 1.5 raised the power of four, gives us approximately five. So we see that in this case, to get the same volume flow rate, we have to increase the pressure by factor five. And that can be very dangerous. So instead of actually blowing up those blood vessels, popping those blood vessels, our body instead chooses to increase the radius only by 50% to basically get that same body and flow rate to our skeletal tissues. So what exactly can we conclude from our discussion?
