A Blowhard Tests of lung capacity show that adults are able to exhale 1.5 liters of air through their mouths in as little as 1.0 second. (a) If a person blows air at this rate through a drinking straw with a diameter of 0.60 cm, what is the speed of air in the straw? (b) If the air from the straw in part (a) is directed horizontally across the upper end of a second straw that is vertical, as shown in Figuer 15-32, to what height does water rise in the vertical straw?
