  3. Sphere packing in a cylinder - Wikipedia

    en.wikipedia.org/wiki/Sphere_packing_in_a_cylinder

    Sphere packing in a cylinder is a three-dimensional packing problem with the objective of packing a given number of identical spheres inside a cylinder of specified diameter and length. For cylinders with diameters on the same order of magnitude as the spheres, such packings result in what are called columnar structures .

    is the Reynolds number with the cylinder diameter as its characteristic length; Pr {\displaystyle \Pr } is the Prandtl number . The Churchill–Bernstein equation is valid for a wide range of Reynolds numbers and Prandtl numbers, as long as the product of the two is greater than or equal to 0.2, as defined above.

  5. Hydraulic diameter - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_diameter

    The hydraulic diameter, D H, is a commonly used term when handling flow in non-circular tubes and channels. Using this term, one can calculate many things in the same way as for a round tube. When the cross-section is uniform along the tube or channel length, it is defined as [1] [2] =, where

  6. Piston motion equations - Wikipedia

    From the geometry shown in the diagram above, the following variables are defined: rod length (distance between piston pin and crank pin) crank radius (distance between crank center and crank pin, i.e. half stroke)

  7. Morison equation - Wikipedia

    en.wikipedia.org/wiki/Morison_equation

    For instance for a circular cylinder of diameter D in oscillatory flow, the reference area per unit cylinder length is = and the cylinder volume per unit cylinder length is =. As a result, F ( t ) {\displaystyle F(t)} is the total force per unit cylinder length:

  8. Tree crown measurement - Wikipedia

    en.wikipedia.org/wiki/Tree_crown_measurement

    The problem then becomes one of determining the diameter of this cylinder so that its volume equals that of the crown of the tree. The volume of each of the individual disks can be calculated by using the formula for the volume of a cylinder:

  9. Sphere packing - Wikipedia

    en.wikipedia.org/wiki/Sphere_packing

    The new proofs involve using the Laplace transform of a carefully chosen modular function to construct a radially symmetric function f such that f and its Fourier transform f̂ both equal 1 at the origin, and both vanish at all other points of the optimal lattice, with f negative outside the central sphere of the packing and f̂ positive.
