WebThe water deficit can be calculated based on the “true” serum sodium concentration, working on the assumption that 60% of the body's weight is water (or about 50% in women). In the following example, a 70-kg male has a corrected serum sodium of 154 mEq/L, with a goal sodium level of 140 mEq/L. WebIt is sometimes convenient to quote water vapour concentration as kg/kg of dry air. This is used in air conditioning calculations and is quoted on psychrometric charts. The following calculations for water vapour concentration in air apply at ground level. Dry air has a molar mass of 0.029 kg. It is denser than water vapour, which has a molar mass
