LOL! I just realized my mistake (and it was a really DUMB one.) I entered in the data into the online cubic equation calculator keeping scientific notation for 3.94*10^-7. The three values it gave me were: -0.4294762187154887, 0.2147310149344237 + i* 0.37193321976168103, and 0.2147310149344237 -...
I am trying to predict the radius of a bubble at 0.4 m deep in a liquid.
I know:
the surface tension of the liquid (T) .002239 kg*m
the pressure outside the bubble at .5 meters depth (Po1) 394.5 kg/m^2
the pressure inside the bubble at .5 meters depth (PI1) 394.723314 kg/m^2
the radius of the...
