When Poiseuille's law is rearranged for flow with pressure remaining constant, what impact would reducing the radius of a tube by 50% have on the gas flow?

Question

Quizplus · Accepted Answer

Poiseuille's law states that flow is proportional to the fourth power of the radius of the tube. Therefore, if the radius is reduced by 50% (or to half its original size), the flow would be reduced to (1/2)^4 = 1/16 of the original flow.
