Solution: When a person inhales, air moves down the bronchus (windpipe) at 16 cm/s. The average flow speed of the air doubles through a constriction in the bronchus. Assuming incompressible flow, find the pressure drop in the constriction. The density of air is 1.29 kg/m 3 1. 0.049536 2. 0.01935 3. 0.062694 4. 0.0559215 5. 0.0327015 6. 0.0435375 7. 0.0234135 8. 0.027864 9. 0.037926 10. 0.0698535
