I promise I haven't forgotten about this, just an update, the testing is all complete, I'll be scanning a few things in and working on the write up here durring the next few days, I should have the results posted by the end of the week.
I did have to change quite a bit from what I originally wanted to do, to give quality results with minimal to no human error, the whole flow rate testing was eliminated as the results gave +-300%, no acceptable IMO, every filter was tested with the 30um contaminant, but only the 2 filters that performed best with the 30um were tested with the 5um, but the 30um provided alot of information about all of them, so in the end it ended up being a bit different that I originally thought up, but there is still alot of great information on everything. I was going to provide like percentage of contaminants that were passed and such by weight, but it ended up that the amount of contaminant that I had to use on each test (so as to not clog the filter but still provide visable results), was too light that the weight of the little bit of oil that couldn't be removed from the media caused large errors in the weight readings. but there are results for everything, so no worries
sorry if these changes bum y'all out, but its what I had to do for the equipment I had available at my disposal, perhaps some day when I have more extra cash, and time I can build a device that will optically count passed particle of different sizes and measure actual flow rates and such. but until that time, this'll have to do.
