Suppose the flow rate of blood in a coronary artery has been reduced to half its normal value by plaque deposits. By what factor has the radius of the artery been reduced, assuming no turbulence occurs?
Strategy
Assuming laminar flow, PoiseuilleĆ¢s law states that
Q = (p2 - p1)pir^4/8nl. We need to compare the artery radius before and after the flow rate reduction.
Answers: 3
and 
, the ratios of their flow rates are :
