There are three main measurements of humidity: absolute, relative and specific. Absolute humidity is the water content of air at a given temperature expressed in gram per cubic metre.Relative humidity, expressed as a percent, measures the current absolute humidity relative to the maximum (highest point) for that temperature.bsolute humidity is the water content of air at a given temperature expressed in gram per cubic metre.

Piston rings for engines with relatively low to medium piston speeds are generally made from cast iron. The rather brittle nature of cast iron is the reason why rings sometimes break under stress. If piston rings are made of steel this will not occur-eg many modern engines now use exotic materials.As speeds rise rings become thinner and have to work a lot harder, so manufacturers move to more durable materials which are outside of the scope of this article.f piston rings are made of steel this will not occur-eg many modern engines now use exotic materials.
