Hi there ....
am trying to release controlled amount of air (bubbles) through a grid of vents at the bottom plate of a
tank filled with liquid .......was banking on surface tension to keep the thick liquid - silicon oil from
entering the 121 vents at the tank bottom (.25mm each)
turns out my naive ideas in physical chem. were wrong ......
details and drawings are downloadable at....http://www.4shared.com/file/3153539/5f33ff0d/sos.html
the liquid is entering the vents at the tank bottom ......seems i need one of the following...
some kindav separation membrane to allow only air passage (air passage has to be uniform all over the
grid)
OR
another liquid thicker than silicon oil under silicon oil ....not entering the 121 (.25mm) vents
OR
Some special air liquid interfacing non return valve to let air thru but block returning liquid etc
anything anyone has to add....or detail in the above?.....
I would be extremely grateful for ANY kind of help or guidance ......these are urgent and desperate hours
do support......deadline only few days away...
cheers
HK
