Parameters for the calculations were extracted from surface tension measurements and NMR diffusometry. The effects of metal ion coordination on the interactions between 4-C12-DTPA and the foaming agents could be linked to a previously established difference in coordination chemistry between the examined metal ions.

How much floatation do I need? - iboats Boating Forums
Each of these sheets is about 2 2/3 cubic feet of volume and provides about 160 pounds of flotation. If you do not want the boat to sink, you need enough flotation volume to equal the total weight of the boat and motor. The volumes need to be concentrated as much as possible in the areas where the heaviest weight is located.
