WebCoughing forces the trachea (windpipe) to contract, which in turn affects the velocity of the air through the trachea. The velocity of the air during coughing can be modeled by v = k(R − r)r2, 0 ≤ r < R where k is a constant, R is the normal radius of the trachea, and r is the radius during coughing. inc authority credit program

The average tracheal … WebAnd we want to know we actually, we have a restriction. We know that our is domain is between half of your resting and the full resting radius. Okay, um, and we want to show that V is a maximum, so that velocity is maximum win. That radius is 2/3 of the resting radius. Okay. And so maximizing means we're going take the derivative. WebWhen you cough, your windpipe contracts. The speed, v(r), with which you expel air depends on the radius, r, of your windpipe. If a is the normal (rest) radius of your windpipe, then for 0 less than or equal to r less than or equal to a, the speed is give; The diaphragm reduces the pressure around your lungs and they expand to fill with air. inc authority discount
