Abstract : Data from sea tests performed on 1/2-inch and 3/8-inch I.D. divers' hose were compared to and found agreeable with the results of an analytical model of air flow in a diver's hose. Assured of the validity of the analytical model, peak air flow rates were analyzed in 3/8-inch I.D. hose and found not near choked flow conditions. It was concluded that 3/8-inch I.D. air hose could supply enough air to support a hard working diver at a 300-ft depth; however, with increasing depths, there is a requirement for increased input air pressure.
