Human Cough To increase the velocity of the air flowing
Chapter 4, Problem 66A(choose chapter or problem)
Human Cough To increase the velocity of the air flowing through the trachea when a human coughs, the body contracts the windpipe, producing a more effective cough. Tuchinsky formulated that the velocity of air that is flowing through the trachea during a cough isV ? C(R0 ? R)R2,where C is a constant based on individual body characteristics, R0 is the radius of the windpipe before the cough, and R is the radius of the windpipe during the cough. It can be shown that the maximum velocity of the cough occurs when dV/dR = 0. Find the value of R that maximizes the velocity. Source: COMAP, Inc.
