Calculation Form Name Calculation Form Description
Bicarbonate, Henderson Calculation Form that Calculates the serum bicarbonate from the serum (SpH and pCO2, based on the Henderson-Hasselbalch equation. Where pH is the acidity in the blood, [HCO3−] is the concentration of bicarbonate in the blood and pCO2 is the partial pressure of carbon dioxide in the arterial blood
Base excess Calculation Form that Calculates the Base excess (BE) with pCO2 and pH as input. Base excess is the amount of strong acid that need to be added to each liter of fully oxygenated blood to return the pH to 7.4 at body temeprature (37 deg) and a pCO2 of 40 mmHg (5.3 kPa). Base excess tresholds: - metabolic alkalosis if too high (more than +2 mEq/L) - metabolic acidosis if too low (less than −2 mEq/L) Based on the Siggaard-Anderson equation and the Henderson-Hasselbalch equation.
Acid Value Calculation Form that Calculates The Acid Value (Aval ) based on Volume of KOH (Vkoh ) , Normality (Nkoh ) and Weight of Oil (Woil ).
Saponification value Calculation Form that Calculates The Saponification Value (Sval ) based on Volume KOH (Blank titration) (Vblank ) , Volume KOH ( Back Titration) (Vback ) , Normality (Nkoh ) and Weight of Oil (Woil ).
Energy of a photon Calculation Form that Calculates The Energy (E ) based on frequency of the particular photon (v ).
Henry’s law for calculating solubility (c) of gases Calculation Form that Calculates The solubility of a gas at a fixed temperature in a particular s (c ) based on partial pressure of the gas (P ).
Activation Energy from Reaction Rate Constants Calculation Form that Second order of activation Energy from Reaction Rate Constants. Activation energy is the amount of energy required to initiate a chemical reaction.
Alcohol by volume ABV Calculation Form that Calcultaes Alcohol by Volume by using a hydrometer to measure the change in specific gravity (SG) of the solution before (SSG) and after fermentation (FSG).
Ideal gas, Molecular weight Calculation Form that Calculates the Molecular weight
Ideal Gas, density Calculation Form that Calculates The density (d ) based on Mass (m ) and Volume (V ).
Ideal Gas Law, moles of a gas Calculation Form that Calculates The Number of moles (n ) based on Mass (m ) and Molecular Weight (MW ).
Mass from density and volume Calculation Form that Calculates mass (m) from density (ρ) and volume (v)
