±0.043 psi Lung air pressure difference moving the normal breaths of a person (only 0.3% of standard atmospheric pressure) [35] [36] 400–900 Pa 0.06–0.13 psi Atmospheric pressure on Mars, < 1% of atmospheric sea-level pressure on Earth [37] 610 Pa 0.089 psi Partial vapor pressure at the triple point of water (611.657 Pa) [38] [39] 10 3 Pa
Using the figures above, we can calculate the maximum pressure at various depths in an offshore oil well. Saltwater is 0.444 psi/ft (2.5% higher than fresh water but this not general and depends on salt concentration in water) Pore pressure in the rock could be as high as 1.0 psi/ft of depth (19.25 lb/gal)
This assumption is commonly made in engineering practice when the Mach number is less than about 0.3. C p {\displaystyle C_{p}} of zero indicates the pressure is the same as the freestream pressure. C p {\displaystyle C_{p}} of one corresponds to the stagnation pressure and indicates a stagnation point .
Ω ξ = ω ξ if ξ > 0, Ω 0 = 1; The functions ψ v (α) for α an ordinal, v an ordinal at most ω, are defined by induction on α as follows: ψ v (α) is the smallest ordinal not in C v (α) where C v (α) is the smallest set such that C v (α) contains all ordinals less than Ω v; C v (α) is closed under ordinal addition
For Reynolds number greater than 4000, the flow is turbulent; the resistance to flow follows the Darcy–Weisbach equation: it is proportional to the square of the mean flow velocity. Over a domain of many orders of magnitude of Re (4000 < Re < 10 8), the friction factor varies less than one order of magnitude (0.006 < f D < 0.06). Within the ...

[4] [5] The unit used in the US is the foot sea water (fsw), based on standard gravity and a sea-water density of 64 lb/ft 3. According to the US Navy Diving Manual, one fsw equals 0.30643 msw, 0.030 643 bar, or 0.444 44 psi, [4] [5] though elsewhere it states that 33 fsw is 14.7 psi (one atmosphere), which gives one fsw equal to about 0.445 ...
The effects of an external pressure of 700 bar on an aluminum cylinder with 5 mm (0.197 in) wall thickness. As an example of varying pressures, a finger can be pressed against a wall without making any lasting impression; however, the same finger pushing a thumbtack can easily damage the wall. Although the force applied to the surface is the ...
