Abstract
The surface area and hence the diameter of a variety of fibers calculated from arealometer data using the Lea and Nurse equation decrease with decreasing sample-bed porosity, indicating that the influence of porosity should be quantitatively determined. Previously suggested correla tions for such data are found to be of little value for fibrous materials. A new correlation is offered which indicates that a definite porosity function is associated with each material.
