WebFeb 20, 2024 · Conversely, decreases in vessel radii, perhaps from plaques in the arteries, can greatly reduce blood flow. If a vessel’s radius is reduced by only 5% (to 0.95 of its original value), the flow rate is reduced to about (0.95)4 = 0.81 of its original value. A 19% decrease in flow is caused by a 5% decrease in radius.
