  2. Flow distribution in manifolds - Wikipedia

    en.wikipedia.org/wiki/Flow_distribution_in_manifolds

    [4] [5] [6] A generalized model of the flow distribution in channel networks of planar fuel cells. [6] Similar to Ohm's law, the pressure drop is assumed to be proportional to the flow rates. The relationship of pressure drop, flow rate and flow resistance is described as Q 2 = ∆P/R. f = 64/Re for laminar flow where Re is the Reynolds number.

  3. Boundary conditions in fluid dynamics - Wikipedia

    en.wikipedia.org/wiki/Boundary_conditions_in...

    Showing outlet flow velocity in a pipe. In outlet boundary conditions, the distribution of all flow variables needs to be specified, mainly flow velocity. This can be thought as a conjunction to inlet boundary condition. This type of boundary conditions is common and specified mostly where outlet velocity is known. [1]

  4. Backflow - Wikipedia

    en.wikipedia.org/wiki/Backflow

    Backflow occurs for one of two reasons, either back pressure or back siphonage. [1] Back pressure is the result of a higher pressure in the system than in its supply, i.e. the system pressure has been increased by some means. This may occur in unvented heating systems, where thermal expansion increases the pressure. Back siphonage is the result ...

  5. Siphon - Wikipedia

    en.wikipedia.org/wiki/Siphon

    Back siphonage is not to be confused with backflow; which is the reversed flow of water from the outlet end to the supply end caused by pressure occurring at the outlet end. [51] Also, building codes usually demand a check valve where the water supply enters a building to prevent backflow into the drinking water system.

  6. Back pressure - Wikipedia

    en.wikipedia.org/wiki/Back_pressure

    Back pressure is the term used for the hydraulic pressure required to create a flow through a chromatography column in high-performance liquid chromatography, the term deriving from the fact that it is generated by the resistance of the column, and exerts its influence backwards on the pump that must supply the flow. Back-pressure is a useful ...

  7. Reverse-flow cylinder head - Wikipedia

    en.wikipedia.org/wiki/Reverse-flow_cylinder_head

    This means that the generally inferior flow of a reverse-flow head is less of a disadvantage. In the early days of turbo charging a reverse-flow head allowed the compressor outlet of a turbocharger to blow directly into the inlet manifold with either a blow-through or draw-through carburettor and no intercooler. This allowed the use of shorter ...

  8. Pressure regulator - Wikipedia

    en.wikipedia.org/wiki/Pressure_regulator

    A typical nominal regulated gauge pressure from a medical oxygen regulator is 3.4 bars (50 psi), for an absolute pressure of approximately 4.4 bar and a pressure ratio of about 4.4 without back pressure, so they will have choked flow in the metering orifices for a downstream (outlet) pressure of up to about 2.3 bar absolute.

  9. Compressor characteristic - Wikipedia

    en.wikipedia.org/wiki/Compressor_characteristic

    Compressor characteristic is a mathematical curve that shows the behaviour of a fluid going through a dynamic compressor.It shows changes in fluid pressure, temperature, entropy, flow rate etc.) with the compressor operating at different speeds.
