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 cost of internal corrosion protection for all appliances includes the use of sacriï¬ cial anodes ($780 million per year), corrosion-re-sistant materials, and internal coatings. The annual cost of external corrosion protection with coatings was estimated at $260 million.he total annual direct cost of corrosion for this sector is more than $0.9 billion, which includes the cost of transporting vehicles ($0.4 billion) and of special-ized packaging ($0.5 billion), as well as costs associated with accidental releases and corrosion-related trans-portation incidents.
