  2. Method of exhaustion - Wikipedia

    en.wikipedia.org/wiki/Method_of_exhaustion

    Proposition 2: The area of circles is proportional to the square of their diameters. [3] Proposition 5: The volumes of two tetrahedra of the same height are proportional to the areas of their triangular bases. [4] Proposition 10: The volume of a cone is a third of the volume of the corresponding cylinder which has the same base and height. [5]

  3. Finite volume method for two dimensional diffusion problem

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

    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. At the boundaries where the temperature or fluxes are known the discretized equation are modified to incorporate the boundary conditions.

  4. 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:

  5. Finite volume method for one-dimensional steady state ...

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

    These equations can be different in nature, e.g. elliptic, parabolic, or hyperbolic. The first well-documented use of this method was by Evans and Harlow (1957) at Los Alamos. The general equation for steady diffusion can easily be derived from the general transport equation for property Φ by deleting transient and convective terms. [1]

  6. Gibbs paradox - Wikipedia

    en.wikipedia.org/wiki/Gibbs_paradox

    The first constraint defines the surface of a 3N-dimensional hypersphere of radius (2mU) 1/2 and the second is a 3N-dimensional hypercube of volume V N. These combine to form a 6N-dimensional hypercylinder. Just as the area of the wall of a cylinder is the circumference of the base times the height, so the area φ of the wall of this ...

    Therefore, the two step process in the classical theory of solving the constraints = (equivalent to solving the admissibility conditions for the initial data) and looking for the gauge orbits (solving the 'evolution' equations) is replaced by a one step process in the quantum theory, namely looking for solutions of the quantum equations ^ =.

  8. Cell Transmission Model - Wikipedia

    en.wikipedia.org/wiki/Cell_Transmission_Model

    The corridor has two signals located at milepost 1 and 2 starting upstream. The signals have a split of 30 seconds and a cycle length of 60 second. With this information, it is a simple matter of iteration of equations (1) for all the cells and time steps. Figure 3 and Table 1 shows the spatial and temporal distribution of density for the case ...

  9. Allen's rule - Wikipedia

    en.wikipedia.org/wiki/Allen's_rule

    A composite cube with a side of 2 has a volume of 8 units 3 but a surface area of only 24 units 2. A rectangular prism two cubes wide, one cube long and four cubes tall has the same volume, but a surface area of 28 units 2. Stacking them in a single column gives 34 units 2.
