The rate of airflow into and out of the lungs can be, Ask an Expert

Academics

The rate of airflow into and out of the lungs can be approximated as a sine wave dV/dt = A sin 2?ft, where f is the breath frequency and t is the time. Determine the maximum flow rate A as a function of tidal volume of the lung, V_Total and the frequency of the breath. If V_Total is 0.5 liter and the breath rate of a person at rest is about 15 breaths per minute, what is the maximum flow rate of the air in and out of the lungs?
