Document Summary

By applying the conservation of energy we arrive at: 1: by expressing the given relationship in terms of the change in potential energy (p1-p2) we achieve. C: using the density of blood (1. 06 g/ml) gives us a simplified. Bernoulli equation, with velocity in units of m/sec. Effect of stenosis: change in flow direction, increased velocity at narrowing, downstream turbulence (within 1 cm, pressure gradient across stenosis, loss of pulsatility, pressure and flow distal to a significant stenosis are. Bernoulli principle: conservation of energy, total energy of fluid (blood) is, potential energy: intravascular pressure (p, potential energy: hydrostatic energy: (pgh, kinetic energy: (blood velocity, 1/2pv^2, p+pgh+1/2pv^2= constant, p1+pgh1+1/2pv1^2= p2+pgh2+1/2pv2^2. Bernoulli"s equation with hydrostatic term: rewriting the equation in terms of the potential energy difference (the pressure gradient) yields. Laminar flow: entrance effect plug flow , laminar flow, steeper parabolic laminar, entrance effect plug flow , exit effect: turbulence, laminar flow.
