Today: Fluid friction Viscous flow though tube Viscous and turbulent drag
Background image of page 2
When blood flows though a blood vessel, it experiences viscous drag, i.e. friction forces . Two blood vessels of equal length are connected in parallel so that they have same pressure drop p . The radius of the first vessel is r 1 . Due to formation of atheriosclerotic plaques, the radius r 2 of the second vessel has been
