  2. Pound per square inch - Wikipedia

    en.wikipedia.org/wiki/Pound_per_square_inch

    For example, a bicycle tire pumped up to 65 psig in a local atmospheric pressure at sea level (14.7 psi) will have a pressure of 79.7 psia (14.7 psi + 65 psi). [ 2 ] [ 3 ] When gauge pressure is referenced to something other than ambient atmospheric pressure, then the unit is pound per square inch differential ( psid ).

  3. Standard penetration test - Wikipedia

    en.wikipedia.org/wiki/Standard_penetration_test

    The standard penetration test (SPT) is an in-situ dynamic penetration test designed to provide information on the geotechnical engineering properties of soil. This test is the most frequently used subsurface exploration drilling test performed worldwide. The test procedure is described in ISO 22476-3, ASTM D1586 [1] and Australian Standards AS ...

  4. Ground pressure - Wikipedia

    en.wikipedia.org/wiki/Ground_pressure

    Ground pressure is the pressure exerted on the ground by the tires or tracks of a motorized vehicle, and is one measure of its potential mobility, [1] especially over soft ground. It also applies to the feet of a walking person or machine. Pressure is measured in the SI unit of pascals (Pa).

    1.5 psi Pressure increase per meter of a water column [26] 10 kPa 1.5 psi Decrease in air pressure when going from Earth sea level to 1000 m elevation [citation needed] +13 kPa +1.9 psi High air pressure for human lung, measured for trumpet player making staccato high notes [48] < +16 kPa +2.3 psi

  6. Oil well control - Wikipedia

    en.wikipedia.org/wiki/Oil_well_control

    HSP = 0.052 × MW × TVD', where MW (Mud Weight or density) is the drilling-fluid density in pounds per gallon (ppg), TVD is the true vertical depth in feet and HSP is the hydrostatic pressure in psi. The 0.052 is needed as the conversion factor to psi unit of HSP. [10] [11] To convert these units to SI units, one can use: 1 ppg ≈ 119.826 ...

  7. Specified minimum yield strength - Wikipedia

    en.wikipedia.org/wiki/Specified_Minimum_Yield...

    Specified Minimum Yield Strength (SMYS) means the specified minimum yield strength for steel pipe manufactured in accordance with a listed specification 1. This is a common term used in the oil and gas industry for steel pipe used under the jurisdiction of the United States Department of Transportation .

  8. .500/450 Nitro Express - Wikipedia

    en.wikipedia.org/wiki/.500/450_Nitro_Express

    Ballistically the .500/450 Nitro Express is almost identical to the .450 Nitro Express and is considered a good large-bore round, suitable for all dangerous game. One prominent user of the .500/450 Nitro Express was Theodore Roosevelt who carried a Holland & Holland double rifle in this calibre, along with a .405 Winchester and a .30-03 during ...

    The head collapsed at a pressure of 525 psi (3,620 kPa), indicating its strength under external pressure was about 10% in excess of that of the shell. The revised Submarine Rescue Chamber had improvements including a soft seal gasket for sealing the submarine/bell interface skirting, and a floor installed to maintain air-space in the bell ...
