  2. Signed number representations - Wikipedia

    en.wikipedia.org/wiki/Signed_number_representations

    The numbers that can be represented with four bits are shown in the comparison table below. The range of numbers that can be represented is asymmetric. If the word has an even number of bits, the magnitude of the largest negative number that can be represented is twice as large as the largest positive number that can be represented, and vice ...

  3. Offset binary - Wikipedia

    en.wikipedia.org/wiki/Offset_binary

    A simple solution to this is to bias the analog signals with a DC offset equal to half of the A/D and D/A converter's range. The resulting digital data then ends up being in offset binary format. [5] Most standard computer CPU chips cannot handle the offset binary format directly [citation needed]. CPU chips typically can only handle signed and ...

  4. Manning formula - Wikipedia

    en.wikipedia.org/wiki/Manning_formula

    The Manning formula or Manning's equation is an empirical formula estimating the average velocity of a liquid in an open channel flow (flowing in a conduit that does not completely enclose the liquid).

  5. Electrical conduit - Wikipedia

    en.wikipedia.org/wiki/Electrical_conduit

    PVC conduit has long been considered the lightest in weight compared to steel conduit materials, and usually lower in cost than other forms of conduit. [3] In North American electrical practice, it is available in thirteen different size and wall thicknesses, [ 4 ] with the thin-wall variety only suitable for embedded use in concrete, and ...

  6. Pipe flow - Wikipedia

    en.wikipedia.org/wiki/Pipe_flow

    In fluid mechanics, pipe flow is a type of fluid flow within a closed conduit, such as a pipe, duct or tube. It is also called as Internal flow. [1] The other type of flow within a conduit is open channel flow. These two types of flow are similar in many ways, but differ in one important aspect.

  7. Offset well - Wikipedia

    en.wikipedia.org/wiki/Offset_well

    Offset data from competing companies is particularly coveted but very hard to obtain due to a profound reluctance by oil and gas operators to share their offset data with competitors. As well planning becomes more complex, regulated and expensive, access to offset well data becomes increasingly important for well planning and benchmarking.

  8. British Standard Pipe - Wikipedia

    en.wikipedia.org/wiki/British_Standard_Pipe

    British Standard Pipe (BSP) is a set of technical standards for screw threads that has been adopted internationally for interconnecting and sealing pipes and fittings by mating an external thread with an internal (female) thread.

  9. Overhead power line - Wikipedia

    en.wikipedia.org/wiki/Overhead_power_line

    An overhead power line is a structure used in electric power transmission and distribution to transmit electrical energy along large distances. It consists of one or more conductors (commonly multiples of three) suspended by towers or poles.
