Air pressure is 1.0 105 N/m2, air density is 1.3 kg/m3, and the density of soft drinks is 1.0 103 kg/m3. If one blows carefully across the top of a straw sticking up 0.100 m from the liquid in a soft drink can, it is possible to make the soft drink rise half way up the straw and stay there. How fast must the air be blown across the top of the straw?
