  2. Archimedes' principle - Wikipedia

    en.wikipedia.org/wiki/Archimedes'_principle

    As this is a cube, the top and bottom surfaces are identical in shape and area, and the pressure difference between the top and bottom of the cube is directly proportional to the depth difference, and the resultant force difference is exactly equal to the weight of the fluid that would occupy the volume of the cube in its absence.

  3. Chvorinov's rule - Wikipedia

    en.wikipedia.org/wiki/Chvorinov's_rule

    Where t is the solidification time, V is the volume of the casting, A is the surface area of the casting that contacts the mold, n is a constant, [clarification needed] and B is the mold constant. This relationship can be expressed more simply as: = Where the modulus M is the ratio of the casting's volume to its surface area:

  4. The Method of Mechanical Theorems - Wikipedia

    en.wikipedia.org/wiki/The_Method_of_Mechanical...

    The region in the y-z plane at any x is the interior of a right triangle of side length whose area is (), so that the total volume is: which can be easily rectified using the mechanical method. Adding to each triangular section a section of a triangular pyramid with area x 2 / 2 {\displaystyle x^{2}/2} balances a prism whose cross section is ...

  5. Hydrostatic weighing - Wikipedia

    en.wikipedia.org/wiki/Hydrostatic_weighing

    Since 1 liter of water weighs 1 kilogram (at 4 °C), it follows that the volume of the block is 1 liter and the density (mass/volume) of the stone is 3 kilograms/liter. Example 2: Consider a larger block of the same stone material as in Example 1 but with a 1-liter cavity inside of the same amount of stone.

  6. Dimensional weight - Wikipedia

    en.wikipedia.org/wiki/Dimensional_weight

    This theoretical weight is the weight of the package at a minimum density chosen by the freight carrier. If the package is below this minimum density, then the actual weight is irrelevant as the freight carrier will charge for the volume of the package as if it were of the chosen density (what the package would weigh at the minimum density).

  7. Method of exhaustion - Wikipedia

    en.wikipedia.org/wiki/Method_of_exhaustion

    Proposition 11: The volume of a cone (or cylinder) of the same height is proportional to the area of the base. [6] Proposition 12: The volume of a cone (or cylinder) that is similar to another is proportional to the cube of the ratio of the diameters of the bases. [7] Proposition 18: The volume of a sphere is proportional to the cube of its ...

  8. On the Sphere and Cylinder - Wikipedia

    en.wikipedia.org/wiki/On_the_Sphere_and_Cylinder

    The ratio of the volume of a sphere to the volume of its circumscribed cylinder is 2:3, as was determined by Archimedes. The principal formulae derived in On the Sphere and Cylinder are those mentioned above: the surface area of the sphere, the volume of the contained ball, and surface area and volume of the cylinder.

  9. Finite volume method for two dimensional diffusion problem

    en.wikipedia.org/wiki/Finite_volume_method_for...

    The face areas in y two dimensional case are : = = and = =. We obtain the distribution of the property i.e. a given two dimensional situation by writing discretized equations of the form of equation (3) at each grid node of the subdivided domain.
