On average, you inhale approximately 1 L of air every 2 seconds. The pressure difference between the outside air and your chest cavity creates this flow. The air flows through your trachea which has a radius of 0.005m and a length of 0.12m. Do not ignore the viscosity of air in this problem. a. What is the velocity of the air moving through the trachea? b. Is this flow laminar or turbulent? Support your answer with calculations. c. What is the pressure in your chest cavity required to create this flow? Assume the outside air has a pressure of 1 atm.
