    21 MPa 3,000 psi Ballistic pressure exerted as high-power bullet strikes a solid bulletproof object [citation needed] 22 MPa 3,200 psi Critical pressure of water 28 MPa 4,100 psi Overpressure caused by the bomb explosion during the Oklahoma City bombing [72] 40 MPa 5,800 psi Water pressure at the depth of the wreck of the Titanic: 69 MPa 10,000 psi

  3. Ultimate tensile strength - Wikipedia

    en.wikipedia.org/wiki/Ultimate_tensile_strength

    In the International System of Units (SI), the unit is the pascal (Pa) (or a multiple thereof, often megapascals (MPa), using the SI prefix mega); or, equivalently to pascals, newtons per square metre (N/m 2). A United States customary unit is pounds per square inch (lb/in 2 or psi). Kilopounds per square inch (ksi, or sometimes kpsi) is equal ...

  4. Pressure head - Wikipedia

    en.wikipedia.org/wiki/Pressure_head

    The venturi meter and manometer is a common type of flow meter which can be used in many fluid applications to convert differential pressure heads into volumetric flow rate, linear fluid speed, or mass flow rate using Bernoulli's principle.

  5. Mean effective pressure - Wikipedia

    en.wikipedia.org/wiki/Mean_effective_pressure

    The mean effective pressure (MEP) is a quantity relating to the operation of a reciprocating engine and is a measure of an engine's capacity to do work that is independent of engine displacement. [1]

  6. Fracture toughness - Wikipedia

    en.wikipedia.org/wiki/Fracture_toughness

    The test is performed by loading steadily at a rate such that K I increases from 0.55 to 2.75 (MPa)/s. During the test, the load and the crack mouth opening displacement (CMOD) is recorded and the test is continued till the maximum load is reached. The critical load P Q is calculated through from the load vs CMOD plot.

  7. Sound pressure - Wikipedia

    en.wikipedia.org/wiki/Sound_pressure

    Acoustic impedance, denoted Z and measured in Pa·m −3 ·s in SI units, is defined by [2] = ^ ^ (), where ^ is the Laplace transform of sound pressure, [citation needed] ^ is the Laplace transform of sound volume flow rate.

  8. Cold inflation pressure - Wikipedia

    en.wikipedia.org/wiki/Cold_inflation_pressure

    Take for example a vehicle which had its cold inflation tire pressure set near Denver (altitude 5300 feet), and is descending towards Los Angeles (altitude 300 feet). The tires could become underinflated by as much as 2.5 psi. Cold inflation pressure should therefore be readjusted after any significant changes in altitude.

  9. Carbon dioxide - Wikipedia

    en.wikipedia.org/wiki/Carbon_dioxide

    In metal carbon dioxide complexes, CO 2 serves as a ligand, which can facilitate the conversion of CO 2 to other chemicals. [25] The reduction of CO 2 to CO is ordinarily a difficult and slow reaction: CO 2 + 2 e − + 2 H + → CO + H 2 O. The redox potential for this reaction near pH 7 is about −0.53 V versus the standard hydrogen electrode.
