LOW-PRESSURE COMPRESSED AIR BREATHING SYSTEMS STUDY. II. MARK V HELMET VENTILATION STUDIES.
Abstract
This report presents experimental results of a testing program for determining mixing effectiveness factors and required ventilation rates for U. S. Navy Mark V diving helmets. Based upon the experimental results and data the following are concluded: Previous ventilation calculations based on a mixing effectiveness factor of 1.0 were conservative; a data base was obtained to more accurately predict required ventilation rates for hard hat diving; The data base for the Mark V should prove to be a valuable tool for comparing the effectiveness of other ventilated helmets.
