The lecture Poiseuille's Law by Jared Rovny is from the course Fluids.
What happens to the resistance of a vein if the radius of the vein is doubled?
What happens to the flow rate through a capillary if the radius is halved, the length of the capillary is quartered and the pressure difference across the capillary is multiplied by 4?
If the arteries are blocked such that there effective radius is reduced to 1/3 their original size, how much more pressure does the heart have to apply in order to keep the same flow rate of blood?
