    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. Pascal (unit) - Wikipedia

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

    The pascal (symbol: Pa) is the unit of pressure in the International System of Units (SI).It is also used to quantify internal pressure, stress, Young's modulus, and ultimate tensile strength.

    The MPA program is a higher professional degree and a postgraduate degree for the public sector and it prepares individuals to serve as managers, executives and policy analysts in the executive arm of local, state/provincial, and federal/national government, and increasingly in non-governmental organization (NGO) and nonprofit sectors; it places a focus on the practices of executive ...

  5. Pressure measurement - Wikipedia

    en.wikipedia.org/wiki/Pressure_measurement

    0.1 mPa is the lowest direct measurement of pressure that is possible with current technology. Other vacuum gauges can measure lower pressures, but only indirectly by measurement of other pressure-dependent properties. These indirect measurements must be calibrated to SI units by a direct measurement, most commonly a McLeod gauge. [22]

  6. United States National System of Marine Protected Areas

    en.wikipedia.org/wiki/United_States_National...

    As a first step in developing the national system of MPAs, the MPA Center compiled an MPA Inventory of all MPAs in U.S. waters. The U.S. has over 1,600 MPAs, ranging from typically small fully protected marine reserves where extractive uses are prohibited to large, multiple-use areas where fishing, diving and other uses are permitted.

  7. Ultimate tensile strength - Wikipedia

    en.wikipedia.org/wiki/Ultimate_tensile_strength

    The ultimate tensile strength of a material is an intensive property; therefore its value does not depend on the size of the test specimen.However, depending on the material, it may be dependent on other factors, such as the preparation of the specimen, the presence or otherwise of surface defects, and the temperature of the test environment and material.

  8. Yield (engineering) - Wikipedia

    en.wikipedia.org/wiki/Yield_(engineering)

    The offset value is given as a subscript, e.g., = MPa or = MPa. [15] For most practical engineering uses, is multiplied by a factor of safety to obtain a lower value of the offset yield point. High strength steel and aluminum alloys do not exhibit a yield point, so this offset yield point is used on these materials.

  9. List of marine protected areas - Wikipedia

    en.wikipedia.org/wiki/List_of_marine_protected_areas

    This definition is intended to make it more difficult to claim MPA status for regions where exploitation of marine resources occurs. If there is no defined long-term goal for conservation and ecological recovery and extraction of marine resources occurs, a region is not considered a marine protected area. [2]
