Get Rq Calculator

The calculated product RQ represents the ratio of the amount of a specific product to its resource consumption. By using the Rq Calculator, you can easily determine this value, which helps in assessing efficiency and performance. Understanding the RQ can guide you in making informed decisions regarding resource allocation. This calculation is essential for businesses aiming to optimize their operations.

Respiratory quotient (RQ) is the ratio between carbon dioxide production and oxygen consumption. The production of carbon dioxide, such as 200 mL/min, normally is slightly less than the oxygen consumption, at 250 mL/min (RQ: 200/250 = 0.8).

The reportable quantity or “RQ” for a hazardous substance is the amount of the material that, if released, requires immediate reporting to the National Response Center (NRC).

Table 117.3—Reportable Quantities of Hazardous Substances Designated Pursuant to Section 311 of the Clean Water Act. Note: The first number under the column headed “RQ” is the reportable quantity in pounds.

Background. The respiratory quotient (RQ), defined as the ratio of carbon dioxide exhaled to oxygen uptake, reflects substrate utilization when energy is expended. Fat and alcohol have RQ values of about 0.7, compared to 1.0 for carbohydrate, and about 0.8 for protein.

Table 117.3 - Reportable Quantities of Hazardous Substances Designated Pursuant to Section 311 of the Clean Water Act. Note: The first number under the column headed “RQ” is the reportable quantity in pounds. The number in parentheses is the metric equivalent in kilograms.

The exact volume of reportable quantities is determined by federal, state, and agency regulations. If a container of a hazardous material is at the reportable quantity level, the labeling must contain the abbreviation "RQ." If that container is involved with a spill, a report must be made.

(2) The letters "RQ" (Reportable Quantity) shall be entered on the shipping paper either before or after the basic description required by 49 CFR 172.202 for each hazardous substance.

The respiratory quotient (RQ) is calculated from the ratio: RQ = CO2 produced / O2 consumed RQ value corresponds to a caloric value for each liter (L) of CO2 produced. ... RQ as measured includes a contribution from the energy produced from protein.
