(water density)*g*(max straw vertical length) = 1 atm. = 101,325 Pa.
Solve for max straw length
Hmax = 101,325/(9.8*1000 kg/m^3)
= 10.3 m
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 atm? Give your answer in meters.
Details and assumptions
1 atm is 101,325 Pa.
The acceleration of gravity is −9.8 m/s2.
The density of water is 1 g/cm3.
