    en.wikipedia.org/wiki/Orders_of_magnitude_(pressure)

    Military submarine max. rated pressure (est.) of Seawolf-class nuclear submarine, at depth of 500 m [65] [66] 10-21 MPa 1,500–3,000 psi Chamber pressure of a high-powered (non-carbon dioxide) air gun 6.9–27 MPa 1,000–4,000 psi Water spray pressure used by pressure washers [67] 9.2 MPa 1,300 psi Atmosphere of Venus [68] 10 7 Pa

  3. Pascal (unit) - Wikipedia

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

    In materials science and engineering, the pascal measures the stiffness, tensile strength and compressive strength of materials. In engineering the megapascal (MPa) is the preferred unit for these uses, because the pascal represents a very small quantity.

  4. Experiments and Observations on Different Kinds of Air

    en.wikipedia.org/wiki/Experiments_and...

    Priestley's first volume of Experiments and Observations on Different Kinds of Air outlined several important discoveries: experiments that would eventually lead to the discovery of photosynthesis and the discovery of several airs: "nitrous air" (nitric oxide, NO), "vapor of spirit of salt" (later called "acid air" or "marine acid air ...

  5. Pressurized water reactor - Wikipedia

    en.wikipedia.org/wiki/Pressurized_water_reactor

    The pressure in the primary coolant loop is typically 15–16 megapascals (150–160 bar), which is notably higher than in other nuclear reactors, and nearly twice that of a boiling water reactor (BWR). As an effect of this, only localized boiling occurs and steam will recondense promptly in the bulk fluid.

  6. Pascal's law - Wikipedia

    en.wikipedia.org/wiki/Pascal's_law

    Pressure in water and air. Pascal's law applies for fluids. Pascal's principle is defined as: A change in pressure at any point in an enclosed incompressible fluid at rest is transmitted equally and undiminished to all points in all directions throughout the fluid, and the force due to the pressure acts at right angles to the enclosing walls.

  7. Science project - Wikipedia

    en.wikipedia.org/wiki/Science_project

    A science project is an educational activity for students involving experiments or construction of models in one of the science disciplines. Students may present their science project at a science fair, so they may also call it a science fair project. Science projects may be classified into four main types.

  9. Experimental uncertainty analysis - Wikipedia

    That g-PDF is plotted with the histogram (black line) and the agreement with the data is very good. Also shown in Figure 2 is a g-PDF curve (red dashed line) for the biased values of T that were used in the previous discussion of bias. Thus the mean of the biased-T g-PDF is at 9.800 − 0.266 m/s 2 (see Table 1).
