If a totalizer associated with the same flow meter was to be set up so as to totalize in U.S. gallons the totalizer K-factor would be 210. Because the K factor is the same for liquid, gas and vapor applications, the value determined from a water calibration is valid for any other fluid. Level bed or load a saved mesh (i.e. Using the Calibration Factor to Determine the Heat of Reaction (enthalpy of reaction) Note, the molar heat of reaction (molar enthalpy of reaction) can be either positive (endothermic reaction) or negative (exothermic reaction). The expanded uncertainty is obtained by multiplying the combined standard uncertainty by a coverage factor, k. Heres what this "k" means, both practically and statistically: The value of the coverage factor, k, is chosen based on the desired level of confidence to be associated with the interval defined by the expanded uncertainty. If the totalizer was to be set to totalize in tenths of a gallon the K-factor would be 210/10 = 21, If the display on a rate meter is required in U.S. gallons per minute, and the K-factor of the flowmeter is 210 pulses per U.S. gallon, then the K-factor entered into the rate meter would be: 210/60 = 3.5. It is a fundamental property, independent of the quantity of material. What is a calibration curve in chemistry?
