Flexible, Spiral-reinforced Circular Ventilation Tubing. System Pressure Loss Tables for Selection of a Fan. A Supplement to Report of Investigations 7085.
NTIS: PB 201 895 :61 pages
This publication comprises tables listing friction loss for a flexible, spiral-reinforced circular ventilation tubing system. The tables were constructed with the following parameters: a friction factor of 62 x 10-10, 10-foot sections of tubing ranging in total length from 100 to 550 feet, air quantities ranging from 1,000 to 15,000 cfm, and one to four 90 deg bends in the tubing. The aim of this publication is to improve ventilation tubing analysis and to provide a method of proper fan selection.
