Page 13 - Archimedes stated that a body immersed in a fluid is buoyed up by a force equal to the weight of the displaced fluid.
Page 1-3 - The amount of any given gas that will dissolve in a liquid at a given temperature is a function of the partial pressure of that gas in contact with the liquid and the solubility coefficient of the gass in the particular liquid.
Page 12 - Specific gravity is the ratio of the density of a substance to the density of water, the values for both substances being determined at the same temperature or at another specified temperature.
Page 17 - Dalton's law states that the total pressure exerted by a mixture of gases is the sum of the pressures that would be exerted by each of the gases if it alone were present and occupied the total volume.
Page 15-19 - Place the heel of one hand on the lower third of the breastbone, the other hand on top of the first. 2. Thrust downward from your shoulders with enough force to depress the breastbone l'/£-2 inches.
Page 7-12 - Fouling A surface-supplied diver's umbilical line may become fouled in mooring lines, wreckage, or underwater structures, or the diver may be trapped by the cave-in of a tunnel or shifting of heavy objects. The surface-supplied diver is in a much better situation to survive since he has a virtually unlimited air supply and generally the ability to communicate, thus facilitating rescue operations. Consequences of fouling may result in fatigue, exposure, and prolonged submergence, with subsequent prolonged...
Page 14-24 - Knowing the amount of air that must be used does not solve the ventilation problem unless there is some way to determine the volume of air actually being used for ventilation. The standard procedure is to open the exhaust valve a given number of turns (or...
Page 69 - Adjust buoyancy if necessary. Whether the diver is weighted neutral or negative will depend on the mission requirements. • Ensure that air supply system, helmet or mask, and communications are functioning properly. If not, corrections must be made prior to descent. Never dive with malfunctioning equipment. • The tender should also verify that all equipment is functioning satisfactorily. • The diver is given permission to descend by the Dive Master.
Page 1-19 - I, no psychophysiological per-formance degradation or any other consistent effect is noted. In zone II, small threshold hearing losses have been found, and there is a perceptible doubling in depth of respiration. In zone III, the zone of distracting discomfort, the symptoms are judgment errors, mental depression, headache, dizziness, nausea, "air hunger," and decrease in visual discrimination.
Page 14 - Time (feet) (minutes) 2. Descent rate- as fast as possible. 3. Ascent rate— 1 ft/min. Do not compensate for slower ascent rates. Compensate for faster ascent rates by halting the ascent. 4. Time at 165 feet- includes time from the surface. 5.
