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.
