The ambient pressure on an object is the pressure of the surrounding medium, such as a gas or liquid, in contact with the object. Within the atmosphere...

and exposure to high ambient pressure have physiological effects that limit the depths and duration possible in ambient pressure diving. Humans are not...

equation, the pressure term may be gauge pressure or absolute pressure, depending on the design of the container and whether it is open to the ambient air or...

in high pressure, high temperature combustion products into kinetic energy by accelerating the gas to high velocity and near-ambient pressure. Simple...

Sound pressure or acoustic pressure is the local pressure deviation from the ambient (average or equilibrium) atmospheric pressure, caused by a sound wave...

ambient pressure from a suitable breathing gas supply. It, therefore, includes the range of physiological effects generally limited to human ambient pressure...

: 445  Gauge pressure (also spelled gage pressure) is the pressure relative to the ambient pressure. Various units are used to express pressure. Some of these...

from an external source, by operational pressure regime: at ambient pressure or in isolation from ambient pressure, by gas mixture: air, oxygen enriched...

various sorts. In ambient pressure diving, the diver is directly exposed to the pressure of the surrounding water. The ambient pressure diver may dive on...

type of gauge. A vacuum gauge is used to measure pressures lower than the ambient atmospheric pressure, which is set as the zero point, in negative values...

in ambient pressure. Various activities are associated with pressure changes. Underwater diving is the most frequently cited example, but pressure changes...

temperature must be high enough that the vapor pressure exceeds the ambient pressure (the atmospheric pressure, primarily). Below that temperature, a water...

saturated vapor pressure equals the ambient pressure. Water supercooled below its normal freezing point has a higher vapor pressure than that of ice...

recycling must not be at too great a pressure difference from the ambient pressure at the diver. An additional back-pressure regulator in this line allows finer...

the gas to a pressure regulator which reduces the pressure to a few bar above ambient pressure, and supplies this intermediate pressure gas to the gas...

room temperature can mean different agreed-upon ranges. In contrast, ambient temperature is the actual temperature, as measured by a thermometer, of...

increase in barometric pressure over ambient pressure is employed increasing the partial pressures of all gases present in the ambient atmosphere. The immediate...
