To suck lemonade of density 1000 kg/m3 up a straw to a maximum height of 3.3 cm, what minimum gauge pressure (in atmospheres) must you produce in your lungs?
I know i need to use P=pgh which equals 1000(9.81)(.033)
which equals 323.73
-Then i divide, so, 323.73/1.0125e5
that equals 3.197e-3
It said that my answer was wrong. It looks good to me. Thanks for the help.
