Percent Volume Definition. Note that volume percent is relative to volume of solution, not volume of solvent. For example, wine is about 12% v/v ethanol. This means there are 12 ml ethanol for every 100 ml of wine. It is important to realize liquid and gas volumes are not necessarily additive.
However, both the material condition and safety of DoD equipment are routinely being undermined by the effects of corrosion. The dollar cost of corrosion to DoD has been estimated by the Government Accountability Office (GAO) to be $10-20 billion per year.
The total cost due to the impact of corrosion for the individual economic sectors was 137.9 billion dollars per year in the following Table. Summary of estimated direct cost of corrosion for industry sectors analyzed in the 2001 study. Example problem 1.2.
