Guide to the Expression of Uncertainty in Measurement (GUM). The proper K-factor depends on the filament, nozzle size, nozzle geometry and printing temperature. The K-factor is calculated by dividing the neutral radius by the thickness of the material using prepared charts, and it ranges from 0.3 to 0.5. This is a calculation of the uncertainty - or potentially how much error there could be - in the measured values. A K-factor of 100 means that there are 100 pulses produced for each gallon of water. A total uncertainty budget is calculated from these uncertainty values for each measurement point, and that is what is presented in this column of the certificate. The bomb, with the known mass of the sample and oxygen, form a closed system no gases escape during the reaction. So in here, you will have some water, a thermometer, a metallic cup, some polystyrene, etc. The irrigation flow meter is a flow meter designed for agricultural irrigation water counting.
