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 same methods were used to develop direct cost data for the nationwide U.S. study and the EPRI study; however, the EPRI study also included indirect costs. It reported total corrosion-related costs of $17.3 billion for the electric power industry vs the $6.9 billion in direct costs estimated by the U.S. study.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.
