In a clinical study of atherosclerosis, researchers note that the 'pressure drop' across a stenosis is higher than predicted by Bernoulli's principle alone.
What physical factor likely accounts for the 'extra' pressure drop?
- The increase in blood density within the narrowing.
- Viscous dissipation (internal friction) within the fluid.
- The conversion of static pressure into potential energy.
- The decrease in the Reynolds number at the stenosis.
