Total hardness calculation
WebAug 27, 2024 · TOTAL PERMANENT HARDNESS = CALCIUM HARDNESS + MAGNESIUM HARDNESS. Based on the molar mass of calcium and magnesium, hardness is calculated with this equation: Hardness = 2.497 (Ca) + 4.118 (Mg) You can see from this equation … WebThe Calculation for Total Hardness got executed after both dependent Analyses were saved and the final Result was marked for submission automatically. Calculation Versioning The same behavior like for Analysis Services applies also for Calculations , so that changes in the Calculation does not affect any of the Analysis created with prior versions of the …
