  3. List of thermal conductivities - Wikipedia

    en.wikipedia.org/wiki/List_of_thermal_conductivities

    Let K 0 is the normal conductivity at one bar (10 5 N/m 2) pressure, K e is its conductivity at special pressure and/or length scale. Let d is a plate distance in meters, P is an air pressure in Pascals (N/m 2 ), T is temperature Kelvin, C is this Lasance constant 7.6 ⋅ 10 −5 m ⋅ K/N and PP is the product P ⋅ d/T .

  4. Saline water - Wikipedia

    en.wikipedia.org/wiki/Saline_water

    Saline water (more commonly known as salt water) is water that contains a high concentration of dissolved salts (mainly sodium chloride). On the United States Geological Survey (USGS) salinity scale, saline water is saltier than brackish water , but less salty than brine .

  5. Haber process - Wikipedia

    en.wikipedia.org/wiki/Haber_process

    Claude proposed to have three or four converters with liquefaction steps in series, thereby avoiding recycling. Most plants continue to use the original Haber process (20 MPa (200 bar; 2,900 psi) and 500 °C (932 °F)), albeit with improved single-pass conversion and lower energy consumption due to process and catalyst optimization.

  6. Shore durometer - Wikipedia

    en.wikipedia.org/wiki/Shore_durometer

    A first-order estimate of the relation between ASTM D2240 type D hardness (for a conical indenter with a 15° half-cone angle) and the elastic modulus of the material being tested is [10] = (+ +), where is the ASTM D2240 type D hardness, and is in MPa.

  7. Magnesium sulfate - Wikipedia

    en.wikipedia.org/wiki/Magnesium_sulfate

    Magnesium sulfate or magnesium sulphate is a chemical compound, a salt with the formula MgSO 4, consisting of magnesium cations Mg 2+ (20.19% by mass) and sulfate anions SO 2− 4.It is a white crystalline solid, soluble in water but not in ethanol.

  8. Methanol (data page) - Wikipedia

    en.wikipedia.org/wiki/Methanol_(data_page)

    Here is a similar formula from the 67th edition of the CRC handbook. Note that the form of this formula as given is a fit to the Clausius–Clapeyron equation, which is a good theoretical starting point for calculating saturation vapor pressures:

  9. Compressive strength - Wikipedia

    en.wikipedia.org/wiki/Compressive_strength

    Measuring the compressive strength of a steel drum. In mechanics, compressive strength (or compression strength) is the capacity of a material or structure to withstand loads tending to reduce size (compression).
