Determination of Total Recirculation, Vacuum High Pressure Nozzle Discharge and other General Characteristics of the Recirculating System of the Standard U. S. Navy Helium Oxygen Deep Sea Diving Helmet under Various Conditions of Depth and Venturi Supply Pressures with Air and HeO2 Mixtures

Abstract

The object of the experiment was to test the recirculating device of the standard U.S. Navy helium-oxygen deep sea diving helmet and to determine the vacuum, high pressure nozzle flow, total recirculation and pressure drop of air, oxygen and HeO2 mixture of about 19.5% O2 in a HeO2 recirculating system under various depths.
