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 Risk of Rust. A study done in the U.S. estimated that it costs $279 billion per year to combat corrosion and repair or replace corroded components. The study further suggests that the cost of corrosion could be reduced by 25 to 30 percent, just by implementing established corrosion control measures.he Risk of Rust.
