In which pO 2 is the chosen maximum partial pressure in oxygen in bar and the FO 2 is the fraction of oxygen in the mixture. For example, if a gas contains 36% oxygen and the maximum pO 2 is 1.4 bar, the MOD (msw) is 10 msw/bar x [(1.4 bar / 0.36) − 1] = 28.9 msw.
The test uses a thick-walled sampling tube, with an outside diameter of 5.01 cm (2 in) and an inside diameter of 3.5 cm (1.375 in), and a length of at least 60 cm (24 in). The sampling tube is driven into the ground at the bottom of a borehole by blows from a hammer with a mass of 63.5 kg (140 lb) falling a distance of 75 cm (30 in).

A schematic depiction of the force balance in a gas disk around a central object, e.g., a star. For a disk of gas around a condensed central object, such as, for example, a protostar, one can derive a disk scale height which is somewhat analogous to the planetary scale height.
The equivalent air depth can be calculated for depths in metres as follows: EAD = (Depth + 10) × (Fraction of N 2 / 0.79) − 10. Working the earlier example, for a nitrox mix containing 64% nitrogen (EAN36) being used at 27 metres, the EAD is:

The nominal definition of field capacity (expressed symbolically as θ fc) is the bulk water content retained in soil at −33 kPa (or −0.33 bar) of hydraulic head or suction pressure. The term originated from Israelsen and West [1] and Frank Veihmeyer and Arthur Hendrickson. [2]
Although carbon dioxide (CO 2) is known to be more narcotic than nitrogen – a rise in end-tidal alveolar partial pressure of CO 2 of 10 millimetres of mercury (13 mbar) caused an impairment of both mental and psychomotor functions of approximately 10% – [5] [2] the effects of carbon dioxide retention are not considered in these calculations, as the concentration of CO 2 in the supplied ...
