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.
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?
If the air from the straw is directed horizontally across the upper end of a second straw that is vertical, as shown in the diagram, to what height does water rise in the vertical straw?
