    ISO 10628 Diagrams for the chemical and petrochemical industry specifies the classification, content, and representation of flow diagrams. It does not apply to electrical engineering diagrams. It does not apply to electrical engineering diagrams.

  3. 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.

  4. Process duct work - Wikipedia

    en.wikipedia.org/wiki/Process_Duct_Work

    Duct logic is the process of planning for duct thermal movement, combined with planning to minimize duct dust dropout. Ducts move with changes in internal temperature. Ducts are assumed to have the same temperature as their internal gasses, which may be up to 900 °F.

  5. Duct (flow) - Wikipedia

    en.wikipedia.org/wiki/Duct_(flow)

    Ducts for air pollution control in a 17000 standard cubic feet per minute regenerative thermal oxidizer (RTO). A round galvanized steel duct connecting to a typical diffuser Fire-resistance rated mechanical shaft with HVAC sheet metal ducting and copper piping, as well as "HOW" (Head-Of-Wall) joint between top of concrete block wall and underside of concrete slab, firestopped with ceramic ...

  6. Hydraulic diameter - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_diameter

    For the limiting case of a very wide duct, i.e. a slot of width b, where b ≫ a, and a is the water depth, then D H = 4a. For a fully filled duct or pipe whose cross-section is a convex regular polygon , the hydraulic diameter is equivalent to the diameter D {\displaystyle D} of a circle inscribed within the wetted perimeter .

  7. Flow process chart - Wikipedia

    en.wikipedia.org/wiki/Flow_process_chart

    Subway Fare Card Machine Flow Process Chart (which doesn't use the ASME standard set of symbols). The flow process chart is a graphical and symbolic representation of the activities performed on the work piece during the operation in industrial engineering.

  8. Turning vanes (HVAC) - Wikipedia

    en.wikipedia.org/wiki/Turning_vanes_(HVAC)

    HVAC turning vanes are sheet metal devices inside of mechanical ductwork used to smoothly direct air inside a duct where there is a change in direction, by reducing resistance and turbulence. See also

  9. Diffuser (thermodynamics) - Wikipedia

    en.wikipedia.org/wiki/Diffuser_(thermodynamics)

    A supersonic diffuser is a duct that decreases in area in the direction of flow which causes the fluid temperature, pressure, and density to increase, and velocity to decrease. These changes occur because the fluid is compressible. Shock waves may also play an important role in a supersonic diffuser.
