  2. Mineral resource classification - Wikipedia

    en.wikipedia.org/wiki/Mineral_resource...

    Mineral Resources are further sub-divided, in order of increasing geological confidence, into inferred, indicated and measured as categories. Inferred Mineral Resource is the part of a mineral resource for which quantity, grade (or quality) and mineral content can be estimated with a low level of confidence. It is inferred from geological ...

  3. Indicated airspeed - Wikipedia

    en.wikipedia.org/wiki/Indicated_airspeed

    A primary flight display with the indicated airspeed (IAS) displayed in the form of a vertical "tape" on the left. Indicated airspeed (IAS) is the airspeed of an aircraft as measured by its pitot-static system [1] and displayed by the airspeed indicator (ASI). [2] This is the pilots' primary airspeed reference.

  4. PERC Reporting Standard - Wikipedia

    en.wikipedia.org/wiki/PERC_Reporting_Standard

    The exact definitions of key terms like 'Modifying Factors', 'Inferred'-, 'Indicated'- and 'Measured Mineral Resources' as well as 'Probable' or 'Proved Mineral Reserves' are documented in the PERC Reporting Standard.

  5. Horsepower - Wikipedia

    en.wikipedia.org/wiki/Horsepower

    Indicated horsepower was a better measure of engine power than nominal horsepower (nhp) because it took account of steam pressure. But unlike later measures such as shaft horsepower (shp) and brake horsepower (bhp), it did not take into account power losses due to the machinery internal frictional losses, such as a piston sliding within the ...

  6. Mean effective pressure - Wikipedia

    en.wikipedia.org/wiki/Mean_effective_pressure

    Despite having the dimension of pressure, MEP cannot be measured. [2] When quoted as an indicated mean effective pressure (IMEP), it may be thought of as the average pressure acting on a piston during the different portions of its cycle. When friction losses are subtracted from the IMEP, the result is the brake mean effective pressure (BMEP).

  7. Indicated airspeed - Wikipedia

    en.wikipedia.org/wiki/Airspeed

    Indicated airspeed is a better measure of power required and lift available than true airspeed. Therefore, IAS is used for controlling the aircraft during taxiing, takeoff, climb, descent, approach or landing. Target speeds for best rate of climb, best range, and best endurance are given in terms of indicated speed.

  8. How to recognize a 'radar-confirmed tornado' - AOL

    When the rain starts to fall, people immediately look to the weather radar to see how long it will last. But when severe weather strikes, meteorologists can use this technology to pinpoint the ...

  9. Total indicator reading - Wikipedia

    en.wikipedia.org/wiki/Total_indicator_reading

    The earliest expansion of "TIR" was total indicated run-out and concerned cylindrical or tapered (conical) parts, where "run-out" (noun) refers to any imperfection of form that causes a rotating part such as a shaft to "run out" (verb), that is, to not rotate with perfect smoothness.
