  2. Standard step method - Wikipedia

    en.wikipedia.org/wiki/Standard_Step_Method

    To find the length of the gradually varied flow transitions, iterate the “step length”, instead of height, at the boundary condition height until equations 4 and 5 agree. (e.g. For an M1 Profile, position 1 would be the downstream condition and you would solve for position two where the height is equal to normal depth.)

  3. Engineering drawing - Wikipedia

    en.wikipedia.org/wiki/Engineering_drawing

    Drawing number (same for every sheet of this document, unique for each technical document of the organization) Sheet number and number of sheets (for example, "Sheet 5/7") Date of issue (when the drawing was made) Traditional locations for the title block are the bottom right (most commonly) or the top right or center.

  4. Isometric projection - Wikipedia

    en.wikipedia.org/wiki/Isometric_projection

    Isometric graph paper can be placed under a normal piece of drawing paper to help achieve the effect without calculation. In a similar way, an isometric view can be obtained in a 3D scene. Starting with the camera aligned parallel to the floor and aligned to the coordinate axes, it is first rotated horizontally (around the vertical axis) by ± ...

  5. Force-directed graph drawing - Wikipedia

    en.wikipedia.org/wiki/Force-directed_graph_drawing

    Force-directed graph drawing algorithms assign forces among the set of edges and the set of nodes of a graph drawing.Typically, spring-like attractive forces based on Hooke's law are used to attract pairs of endpoints of the graph's edges towards each other, while simultaneously repulsive forces like those of electrically charged particles based on Coulomb's law are used to separate all pairs ...

  6. Technical drawing - Wikipedia

    en.wikipedia.org/wiki/Technical_drawing

    An exploded-view drawing is a technical drawing of an object that shows the relationship or order of assembly of the various parts. [13] It shows the components of an object slightly separated by distance or suspended in surrounding space in the case of a three- dimensional exploded diagram.

  7. List of equations in fluid mechanics - Wikipedia

    en.wikipedia.org/wiki/List_of_equations_in_fluid...

    Flux F through a surface, dS is the differential vector area element, n is the unit normal to the surface. Left: No flux passes in the surface, the maximum amount flows normal to the surface.

  8. Slide rule - Wikipedia

    en.wikipedia.org/wiki/Slide_rule

    Quadratic equations of the form + + = can be solved by first reducing the equation to the form + = (where = / and = /), and then aligning the index ("1") of the C scale to the value on the D scale. The cursor is then moved along the rule until a position is found where the numbers on the CI and D scales add up to p {\displaystyle p} .

  9. Engineering drawing abbreviations and symbols - Wikipedia

    en.wikipedia.org/wiki/Engineering_drawing...

    A list, usually tabular and often on the drawing (if not accompanying the drawing on a separate sheet), listing the parts needed in an assembly, including subparts, standard parts, and hardware. There is no consistently enforced distinction between an L/M, a BoM, or a P/L. PLM: product lifecycle management; plant lifecycle management: See also ...
