GCV of the coal. 3. GCV of the coal is decreased over a period as a result of the storage in the coal yard. Consequently, CERC Tariff Regulation 2019 has stipulated that GCV of the coal as received in kCal/kg is reduced by 85 Kcal/Kg on account of variation during storage at generating station. Accordingly, GCV ARB

Compute the geometric mean, geometric standard deviation, and geometric
Kirkwood's proposal for the geometric coefficient of variation (GCV) is not generally used. Instead, the accepted definition of the GCV is GCV = sqrt(exp(σ 2) – 1), which is the definition that is used in SAS. The estimate for the GCV is sqrt(exp(s 2) – 1). You can use these formulas to compute the geometric statistics for any positive data.
What is GCV ARB? – Heimduo
What is the difference between ARB and ADB? ARB puts all variables into consideration and uses the total weight as the basis of measurement. ADB (air-dried) basis neglect the presence of moistures other than inherent moisture unlike ARB which uses total moisture. This results in different measured GCV on different Basis.

However, the GCV adb takes the Analysis Moisture into account which actually depends on the lab conditions (temperature, humidity, air pressure, etc.) which may differ substantially. Therefore, the GCV adb is not a very reliable result on which to trade when considering the calorific value and the ambiguities associated with AM.

PharmGKB summary: Acyclovir/Ganciclovir Pathway
Clinical Pharmacokinetics. As structural analogs, ACV and GCV present similar pharmacokinetics profiles. Their poor oral absorption limits their respective bioavailabilities (around 10%–20% for ACV and 8.5% for GCV, with the latter being slightly improved by simultaneous food intake [6–8]) and supports their intravenous administration.This …

GCV [ADB Definition | Law Insider
The petitioner suggested the figure of 4338/Kcal/kg, whereas the quotation containing the base price of coal of `4300/tonne, indicates a GCV (ADB) of 5500±100 Kcal/kg. Coal will be rejected if the GCV is less than 4700 KCal/Kg. No correction shall be applied in case of increase in measured GCV (ADB) above the base parameter value.
