In building engineering, the amount of water absorbed by a brick or other porous building material, expressed in grams or ounces per minute.

The environmental rate of decrease with height for an atmospheric variable or temperature: The atmospheric lapse rate is the rate of decrease with height and not simply the rate of change.

While most often applied to the Earth's atmosphere, the concept can be extended to any gravitationally supported ball of gas.

In other words, the atmospheric lapse rate involves the decrease of temperature with elevation in the atmosphere.

The "environmental lapse rate" is determined by the distribution of temperature in the vertical at a given time and place and should be carefully distinguished from the process lapse rate, which applies to an individual air parcel.

1. The burning rate of any substance.
2. The rate at which a substance burns.

The number of characters that can be moved from an RFID (Radio-Frequency Identification) tag to a reader within a given time: The measure of data transfer rate or the speed with which a computer device transmits information are also used to quantify how fast readers can read the information on the RFID tag.

Data transfer rate differs from the "read rate" which refers to how many tags can be read within a given period of time.

The speed or pace at which populations are made weaker or smaller because of a lack of births and immigration: The annual statistics gathered by the government tracked the dilution rates of the various groups of people.

The number of errors per number of transactions.

The rate at which a particular substance will be changed into a gas when compared to the rate of a known substance; such as, ethyl ether: "The evaporation rate is especially useful for health and fire-hazard considerations."

The rate at which the temperature of the atmosphere falls as altitude increases.

The actual speed of boring holes with drilling tools: The penetration rates of the drills were recorded for future evaluations.

1. Often used to describe the number of tags that can be read within a given period. 2. The maximum rate at which data can be read from a tag.

In a given population, a statement of the total number of children that would be born to a representative woman, if she were to live to the end of her reproductive years and have children at various age levels in accordance with the prevailing age-specific fertility rates.

1. The rate at which information is transferred to a tag, written into the tag's memory and verified as being correct.
2. The rate at which information is transferred to a tag.
