dc.description.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. en
