Longest straw

Classical Mechanics Level 2

I drink from a glass of water with a vertical straw. What's the longest straw I can use and still drink water if the ambient pressure is \(1~\mbox{atm}\)? Give your answer in meters.

Details and assumptions

  • \(1~\mbox{atm}\) is \(101,325~\mbox{Pa}\).
  • The acceleration of gravity is \(-9.8~\mbox{m/s}^2\).
  • The density of water is \(1~\mbox{g/cm}^3\).
