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.Part AIf a person blows air at this rate through a drinking straw with a diameter of 0.61cm , what is the speed of air in the straw? Express your answer using two significant figures. V = m/s Part 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 the figure(Figure 1) , to what height does water rise in the vertical straw? Express your answer using two significant figures. h = m
