The rate at which a metal powder will flow through an orifice in a standard instrument, and/or according to a specified procedure.
Industry:Mining
The rate at which a sound wave travels through a medium. Velocity is equal to the square root of the bulk modulus divided by density.
Industry:Mining
The rate at which air will remove heat from a body and may be measured dry or wet. The cooling power of air, as determined by the kata thermometer, is one of the basic environmental standards.
Industry:Mining
The rate of a chemical reaction is directly proportional to the molecular concentrations of the reacting substances.
Industry:Mining
The rate of change of a quantity in the direction of the vertical.
Industry:Mining
The rate at which an electrode is consumed by an arc in units of mass per time per arc current.
Industry:Mining
The rate of motion of air in a given direction; in mine ventilation it is usually expressed in meters per second. This is usually measured conducting a vane anemometer traverse over a selected cross section, the area of which is also measured.
Industry:Mining
The rate at which an electrode is consumed by an arc in units of mass per time per arc power.
Industry:Mining
The rate at which an electrode is consumed by an arc in units of mass per time.
Industry:Mining
The rate of the increase in the drift angle that is generally expressed as the number of degrees increase for a specific drilled footage; e.g., 2 degrees per 100 ft (30.5 m).
