  2. Mesh (scale) - Wikipedia

    en.wikipedia.org/wiki/Mesh_(scale)

    Mesh is a measurement of particle size often used in determining the particle-size distribution of a granular material. For example, a sample from a truckload of peanuts may be placed atop a mesh with 5 mm openings. When the mesh is shaken, small broken pieces and dust pass through the mesh while whole peanuts are retained on the mesh.

  3. Sieve analysis - Wikipedia

    en.wikipedia.org/wiki/Sieve_analysis

    A sieve analysis (or gradation test) is a practice or procedure used in geology, civil engineering, [1] and chemical engineering [2] to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction ...

  4. Types of mesh - Wikipedia

    en.wikipedia.org/wiki/Types_of_mesh

    See also mesh generation and principles of grid generation. In two dimensions, flipping and smoothing are powerful tools for adapting a poor mesh into a good mesh. Flipping involves combining two triangles to form a quadrilateral, then splitting the quadrilateral in the other direction to produce two new triangles.

  5. Particle-size distribution - Wikipedia

    en.wikipedia.org/wiki/Particle-size_distribution

    In granulometry, the particle-size distribution (PSD) of a powder, or granular material, or particles dispersed in fluid, is a list of values or a mathematical function that defines the relative amount, typically by mass, of particles present according to size. [1]

    Calculate the maximum allowable vapor velocity in the vessel by using the Souders–Brown equation: = where v is the maximum allowable vapor velocity in m/s ρ L is the liquid density in kg/m 3 ρ V is the vapor density in kg/m 3

    en.wikipedia.org/wiki/Chinois

    A chinois (UK: / ˈ ʃ ɪ n w ɑː, ˈ ʃ iː n w ɑː / SHIN-wah, SHEE-nwah, US: / ʃ iː ˈ n w ɑː / shee-NWAH, French: ⓘ), also known as a bouillon strainer, is a conical sieve with an extremely fine mesh. It is used to strain custards, purees, soups, and sauces, producing a very smooth texture. It can also be used to dust food with a ...

  8. Mesh analysis - Wikipedia

    en.wikipedia.org/wiki/Mesh_analysis

    Mesh analysis (or the mesh current method) is a circuit analysis method for planar circuits. Planar circuits are circuits that can be drawn on a plane surface with no wires crossing each other. A more general technique, called loop analysis (with the corresponding network variables called loop currents ) can be applied to any circuit, planar or ...

  9. Spot welding - Wikipedia

    en.wikipedia.org/wiki/Spot_welding

    The voltage needed for welding depends on the resistance of the material to be welded, the sheet thickness and desired size of the nugget. When welding a common combination like 1.0 + 1.0 mm sheet steel, the voltage between the electrodes is only about 1.5 V at the start of the weld but can fall as low as 1 V at the end of the weld.
