  2. Hydrostatic test - Wikipedia

    en.wikipedia.org/wiki/Hydrostatic_test

    For example, if a cylinder was rated to DOT-2015 PSI (approximately 139 bar), it would be tested at around 3360 PSI (approximately 232 bar). Water is commonly used because it is cheap and easily available, and is usually harmless to the system to be tested. Hydraulic fluids and oils may be specified where contamination with water could cause ...

  3. Drain-induced barrier lowering - Wikipedia

    en.wikipedia.org/wiki/Drain-induced_barrier_lowering

    As drain voltage is increased, the depletion region of the p-n junction between the drain and body increases in size and extends under the gate, so the drain assumes a greater portion of the burden of balancing depletion region charge, leaving a smaller burden for the gate. As a result, the charge present on the gate retains charge balance by ...

  4. Water detector - Wikipedia

    en.wikipedia.org/wiki/Water_detector

    Electronic components used to make a simple water detector: battery, resistor, transistor, water sensor and piezoelectric buzzer for audible alert A water detector is an electronic device that is designed to detect the presence of water for purposes such as to provide an alert in time to allow the prevention of water leakage.

  5. Water flow test - Wikipedia

    en.wikipedia.org/wiki/Water_flow_test

    First, a static pressure gauge is attached to the test hydrant and the static water pressure is measured at the test hydrant. Second, the flow hydrant opened to allow water to flow in a fully open condition. Simultaneously the pitot tube pressure is recorded from the flow hydrant while the residual pressure is measured from the test hydrant.

  6. Antistatic device - Wikipedia

    en.wikipedia.org/wiki/Antistatic_device

    An ionizing bar, sometimes referred to as a static bar, is a type of industrial equipment used for removing static electricity from a production line to dissipate static cling and other such phenomena that would disrupt the line. It is important in the manufacturing and printing industries, although it can be used in other applications as well.

  7. Contact resistance - Wikipedia

    en.wikipedia.org/wiki/Contact_resistance

    Contact resistance values are typically small (in the microohm to milliohm range). Contact resistance can cause significant voltage drops and heating in circuits with high current. Because contact resistance adds to the intrinsic resistance of the conductors, it can cause significant measurement errors when exact resistance values are needed.

  8. Drain (plumbing) - Wikipedia

    en.wikipedia.org/wiki/Drain_(plumbing)

    Pool drain vortex as viewed from above the water at Grange Park wading pool Underwater view of drain, showing vortex-formation phenomenon. A drain is the primary vessel or conduit for unwanted water or waste liquids to flow away, either to a more useful area, funnelled into a receptacle, or run into sewers or stormwater mains as waste discharge to be released or processed.

  9. Hydraulic analogy - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_analogy

    If taken too far, the water analogy can create misconceptions. Negative transfer can occur when there is a mismatch between phenomena in the source (hydraulics) and the corresponding phenomena in the target (electronics). [2] For the analogy to be useful, one must remain aware of the regions where electricity and water behave very differently.
