"One of the most important factors that influence the selection of a fan or blower for circulating a desired quantity of air through mine workings is the total pressure that is required to overcome the resistance of the airways. Ordinarily, the major portion of this resistance is that caused by friction of the moving air on the surface of the airways. The pressure that is required to overcome this frictional resistance is calculated by means of the friction formula"--Introduction, page 1.
