  2. MAP sensor - Wikipedia

    en.wikipedia.org/wiki/MAP_sensor

    Boost pressure is relative to absolute pressure - as one increases or decreases, so does the other. It is a one-to-one relationship with an offset of -100 kPa for boost pressure. Thus, a MAP sensor will always read 100 kPa more than a boost sensor measuring the same conditions. A MAP sensor will never display a negative reading because it is ...

    en.wikipedia.org/wiki/Knudsen_absolute_manometer

    Pressure is determined by the interaction of particles with a surface, its kinetic energy, and is temperature dependent. When a particle hits a hotter surface, heat transfer will take place and the particle will gain energy. When a particle hits a colder surface, the opposite occurs.

  5. Manifold vacuum - Wikipedia

    en.wikipedia.org/wiki/Manifold_vacuum

    Manifold vacuum, or engine vacuum in a petrol engine is the difference in air pressure between the engine's intake manifold and Earth's atmosphere.. Manifold vacuum is an effect of a piston's movement on the induction stroke and the airflow through a throttle in the intervening carburetor or throttle body leading to the intake manifold.

  6. Flow distribution in manifolds - Wikipedia

    The n is the number of ports and L the length of the manifold (Fig. 2). This is fundamental of manifold and network models. Thus, a T-junction (Fig. 3) can be represented by two Bernoulli equations according to two flow outlets. A flow in manifold can be represented by a channel network model.

    en.wikipedia.org/wiki/Standard_litre_per_minute

    Until 1982, STP was defined as a temperature of 273.15 K (0 °C, 32 °F) and an absolute pressure of 101.325 kPa (1 atm). Since 1982, STP is defined as a temperature of 273.15 K (0 °C, 32 °F) and an absolute pressure of 100 kPa (1 bar). Conversions between each volume flow metric are calculated using the following formulas: Prior to 1982,
