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.
âââââââââ-. The Hard Numbers on Corrosion. Hereâs why corrosion costs are over $1 trillion today (compared to the oft-quoted $276 billion from 1998). First, the math: In 1998, the direct cost of corrosion was 3.1% of GDP is $276 Billion. This is the oft-cited number referred to in the NACE cost of corrosion study.In 2013, the direct cost of corrosion was 3.1% of the 15.1 Trillion U.S. GDP, which in June 2013 is estimated to equal to $500.7 Billion.irst, the math: In 1998, the direct cost of corrosion was 3.1% of GDP is $276 Billion.
