  2. Actual cubic feet per minute - Wikipedia

    en.wikipedia.org/wiki/Actual_cubic_feet_per_minute

    Actual cubic feet per minute (ACFM) is a unit of volumetric flow. It is commonly used by manufacturers of blowers and compressors. [1] This is the actual gas delivery with reference to inlet conditions, whereas cubic foot per minute (CFM) is an unqualified term and should only be used in general and never accepted as a specific definition without explanation.

  3. Standard cubic feet per minute - Wikipedia

    en.wikipedia.org/wiki/Standard_cubic_feet_per_minute

    Actual cubic foot per minute (ACFM) is the volume of gas flowing anywhere in a system, taking into account its temperature and pressure. If the system were moving a gas at exactly the "standard" condition, then ACFM would equal SCFM. This usually is not the case as the most important change between these two definitions is the pressure.

    The motor size constant and motor velocity constant (, alternatively called the back EMF constant) are values used to describe characteristics of electrical motors. Motor constant [ edit ]

  5. Airwatt - Wikipedia

    en.wikipedia.org/wiki/Airwatt

    The airwatt is a valuable measurement of vacuum cleaner motor efficiency because it represents the power carried by the fluid flow (in the case of a typical household vacuum, this fluid is air). The power of the airflow is equal to the product of pressure and volumetric flow rate.

    Motor modifications are limited to strict motor specifications and equipment alterations defined and published in APBA category rule books for these outboard hydroplane racing classes. Both stock and modified outboard classes run on a circular or triangular race course using a 3-minute "milling warm-up" period before a " flying " clock start.

    Actual Cubic Feet per Minute (ACFM) is the volume of gas flowing anywhere in a system, independent of its temperature and pressure. If the system were moving air at exactly the "standard" condition, then ACFM would equal SCFM. Unfortunately, this usually is not the case as the most important change between these two definitions is the pressure.

    The outdrive unit of a boat with sterndrive. A sterndrive or inboard/outboard drive (I/O) is a form of marine propulsion which combines inboard power with outboard drive. The engine sits just forward of the transom while the drive unit (outdrive or drive leg) lies outside the hull.
