  2. Tube drawing - Wikipedia

    en.wikipedia.org/wiki/Tube_drawing

    Tube sinking, also known as free tube drawing, reduces the diameter of the tube without a mandrel inside the tube. The inner diameter is determined by the inner and outer diameter of the stock tube, the outer diameter of the final product, the length of the die landing, the amount of back tension, and the friction between the tube and the die.

  3. Tube (structure) - Wikipedia

    en.wikipedia.org/wiki/Tube_(structure)

    By 1963, a new structural system of framed tubes had appeared in skyscraper design and construction. Fazlur Rahman Khan, a structural engineer from Bangladesh (then called East Pakistan) who worked at Skidmore, Owings & Merrill, defined the framed tube structure as "a three dimensional space structure composed of three, four, or possibly more frames, braced frames, or shear walls, joined at or ...

  4. Piping and instrumentation diagram - Wikipedia

    en.wikipedia.org/wiki/Piping_and_instrumentation...

    Piping and instrumentation diagram of pump with storage tank. Symbols according to EN ISO 10628 and EN 62424. A more complex example of a P&ID. A piping and instrumentation diagram (P&ID) is defined as follows: A diagram which shows the interconnection of process equipment and the instrumentation used to control the process.

  5. Process flow diagram - Wikipedia

    en.wikipedia.org/wiki/Process_flow_diagram

    A process flow diagram (PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations.

  6. Channel pattern - Wikipedia

    en.wikipedia.org/wiki/Channel_pattern

    These channels are classified as a composite form of which the individual channel belts may have braided, meandering or straight channels. Although similar to, and even encompass other channel types, anastomosed rivers are their own entity and have just begun to be studied by geologists , revealing that much is still unknown.

  7. Hydraulic jumps in rectangular channels - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_Jumps_in...

    This example is a very basic hydraulic jump situation where the flow approaches at a supercritical depth, y 1, and jumps to its subcritical conjugate depth, y 2, in order to obtain the necessary energy to continue moving down the channel with the given flow rate, q. Figure 6. M-y Diagram

  8. Plug flow reactor model - Wikipedia

    en.wikipedia.org/wiki/Plug_flow_reactor_model

    The plug flow reactor model (PFR, sometimes called continuous tubular reactor, CTR, or piston flow reactors) is a model used to describe chemical reactions in continuous, flowing systems of cylindrical geometry.

  9. Tube bending - Wikipedia

    en.wikipedia.org/wiki/Tube_bending

    Press bending is probably the first bending process used on cold pipes and tubing. [clarification needed] In this process a die in the shape of the bend is pressed against the pipe forcing the pipe to fit the shape of the bend. Because the pipe is not supported internally there is some deformation of the shape of the pipe, resulting in an oval ...
