ABSTRACT

A small amount of a liquid (such as water) that makes something wet or moist. Moisture is simply water diffused in a relatively small quantity. Nearly all materials contain at least a diminutive volume of moisture as a component of the molecular makeup. It is the quantity of water contained in a material. Moisture content express the amount of water present in a moist sample.Moisture content can be expressed on wet or dry basis. Moisture content on dry basis is the amount of water per unit mass of dry solids in the sample. Moisture content on wet basis is the amount of water per unit mass of moist - or wet – sample. Moisture content analysis is a critical component of material quality and essentially a function of quality control in most production and laboratory facilities. The moisture content influences the physical properties of a substance such as weight, density, viscosity, Refractive index, electrical,Conductivity and many more.
