  2. Turnover number - Wikipedia

    en.wikipedia.org/wiki/Turnover_number

    In chemistry, the term "turnover number" has two distinct meanings.. In enzymology, the turnover number (k cat) is defined as the limiting number of chemical conversions of substrate molecules per second that a single active site will execute for a given enzyme concentration [E T] for enzymes with two or more active sites.

    en.wikipedia.org/wiki/Indicated_airspeed

    convert CAS to equivalent airspeed (EAS) by allowing for compressibility effects (not necessary at slow speed or low altitude); EAS is used by aircraft engineers and some very high-altitude flying aircraft such as the U-2 and the SR-71; convert EAS to true airspeed (TAS) by allowing for differences in density altitude.

  5. 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.

  6. Air compressor - Wikipedia

    en.wikipedia.org/wiki/Air_compressor

    Air compressor supplies air into a nail gun.. An air compressor is a machine that takes ambient air from the surroundings and discharges it at a higher pressure. It is an application of a gas compressor and a pneumatic device that converts mechanical power (from an electric motor, diesel or gasoline engine, etc.) into potential energy stored in compressed air, which has many uses.

  7. Hydraulic compressor - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_compressor

    A hydraulic compressor is a means of compressing air using hydraulic energy. There are two very different types of machines referred to as hydraulic compressors. One type is a mechanical air compressor that is driven by a hydraulic motor. It is a method of converting hydraulic power to pneumatic power. [1]

  8. Overall pressure ratio - Wikipedia

    en.wikipedia.org/wiki/Overall_pressure_ratio

    In aeronautical engineering, overall pressure ratio, or overall compression ratio, is the amount of times the pressure increases due to ram compression and the work done by the compressor stages. The compressor pressure ratio is the ratio of the stagnation pressures at the front and rear of the compressor of a gas turbine.

  9. Kaeser Compressors - Wikipedia

    en.wikipedia.org/wiki/Kaeser_Compressors

    Kaeser’s design philosophy remains to develop larger, slower running air-ends. Air-ends turning at slower speeds deliver more compressed air for the same drive power (up to 20% more efficient than conventional screw designs). Oil flooding at the point of compression provides cleaning, lubrication and cooling, which contributes to air-end ...
