Molecular formula : CAS :
nature : solid, fluid or powder layer along a given surface (glossy) in the direction so that the sliding surface or displacement by the role of stress as a shear stress, the unit of vapor. In chemical engineering, for the one-dimensional flow of Newtonian fluid type, shear stress can be expressed as the following formula : τ =. - Μ for the fluid viscosity, du_{x} / dy for the x direction, the shear rate.
