    0.8–2 MPa 120–290 psi Pressure used in boilers of steam locomotives [citation needed] 1.1 MPa 162 psi Pressure of an average human bite [citation needed] 2.8–8.3 MPa 400–1,200 psi Pressure of carbon dioxide propellant in a paintball gun [64] 5 MPa 700 psi Water pressure of the output of a coin-operated car wash spray nozzle [58] 5 MPa ...

  3. PDFtk - Wikipedia

    en.wikipedia.org/wiki/Pdftk

    PDFtk (short for PDF Toolkit) is a toolkit for manipulating Portable Document Format (PDF) documents. [3] [4] It runs on Linux, Windows and macOS. [5]It comes in three versions: PDFtk Server (open-source command-line tool), PDFtk Free and PDFtk Pro (proprietary paid). [2]

  4. Fracture toughness - Wikipedia

    en.wikipedia.org/wiki/Fracture_toughness

    Fracture toughness varies by approximately 4 orders of magnitude across materials. Metals hold the highest values of fracture toughness. Cracks cannot easily propagate in tough materials, making metals highly resistant to cracking under stress and gives their stress–strain curve a large zone of plastic flow.

  5. Remote Differential Compression - Wikipedia

    en.wikipedia.org/wiki/Remote_Differential...

    Since many types of file changes can cause the file contents to move without other significant change (for example, a small insertion or deletion at the beginning of a file can cause the rest of the file to become misaligned to the original content) the blocks used for comparison are not based on static arbitrary cut points but on cut points ...

  6. List of viscosities - Wikipedia

    en.wikipedia.org/wiki/List_of_viscosities

    For gas, the dynamic viscosity is usually in the range of 10 to 20 microPascal-seconds, or 0.01 to 0.02 centiPoise. The density is usually on the order of 0.5 to 5 kg/m^3. Consequently, its kinematic viscosity is around 2 to 40 centiStokes.

  7. Bar (unit) - Wikipedia

    en.wikipedia.org/wiki/Bar_(unit)

    The kilobar, equivalent to 100 MPa, is commonly used in geological systems, particularly in experimental petrology. The abbreviations "bar(a)" and "bara" are sometimes used to indicate absolute pressures, and "bar(g)" and "barg" for gauge pressures. The usage is deprecated but still prevails in the oil industry (often by capitalized "BarG" and ...

    en.wikipedia.org/wiki/Microsoft_Windows_SDK

    Platform SDK is the successor of the original Microsoft Windows SDK for Windows 3.1x and Microsoft Win32 SDK for Windows 9x.It was released in 1999 and is the oldest SDK. Platform SDK contains compilers, tools, documentations, header files, libraries and samples needed for software development on IA-32, x64 and IA-64 CPU architectures. .

  9. Pressure measurement - Wikipedia

    en.wikipedia.org/wiki/Pressure_measurement

    The current depends on the number of ions, which depends on the pressure in the gauge. Hot cathode gauges are accurate from 10 −3 Torr to 1010 Torr. The principle behind cold cathode version is the same, except that electrons are produced in the discharge of a high voltage. Cold cathode gauges are accurate from 10 −2 Torr to 10 −9 ...
