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 annual cost of corrosion to the United States was estimated in Uhligs report to be $5.5 billion or 2.1 percent of the 1949 GNP.This study attempted to measure the total costs associated to corroding components by summing up the cost for both the owner and operator (direct cost) and for the users (indirect cost).
