Document Summary
Radius of the vessel: compare the flow rate for a vessel with a radius of 3 mm or one with a radius of 2 mm. Assume that the pressure differential, length, and viscosity are the same for each vessel: r1= 3^4= 81, r2= 2^4= 16, 81/16= -5 so you are going from 5 to 1 , which would be 80% reduction. 12. according to bernoili"s principle, what energy decreases when blood velocity is increased: potential energy (pressure) decreases when kinetic energy (blood velocity) The flow through a conduit vessel is determined by changes in the pressure differential. A change in either the proximal pressure or distal pressure affects flow: what term describes the complete loss of laminar flow distal to stenosis , turbulence. 15. list three factors that comprise reynolds" number: blood viscosity, flow velocity, vessel diameter, and blood density. List and describe the flow characteristics present at each of the five references points on.
