Water Hp = (GPM) x (Total Head, ft) (3,960 gal/min/ft) Brake Hp = (GPM) x (Total Head, ft) (3,960) x (Pump % Efficiency) Motor Hp = (GPM ) x ( Total Head, ft) (3,960) x (Pump % Eff.) x (Motor % Eff.) “Wire to Water” Efficiency = (Motor, % Efficiency x Pump % Efficiency)
8 mar 2020 · The general number of equivalents formula is. E = MW/charge number. Where MW is the molecular weight of the compound and charge number is the number of proton- or hydroxide-equivalents the compound contains. Examples with different acids and bases help illustrate how this works in practice.
In chemistry, equivalent weight (also known as gram equivalent[1] or equivalent mass) is the mass of one equivalent, that is the mass of a given substance which will combine with or displace a fixed quantity of another substance.
The equivalent masses of acids, bases, and salts are calculated as follows: Equivalent mass of an acid = molecular mass of the acid/basicity. Equivalent mass of a base = molecular mass of the base/acidity. Equivalent mass of a salt = molecular mass of the salt/total positive valency of metal atoms.
What is the mass/volume % of glucose solution prepared by dissolving 50 g glucose in enough water to make 1000 mL of solution? Solution. Given: Solute = 50.0 g, and Solution = 1000 mL, Desired: Mass/volume % glucose solution? Formula: \begin{equation}
21 lis 2023 · The Equivalent Weight (EW) formula is: EW = Molar Mass / n number of equivalents. Where "n" number of equivalents is the quantity of charge depending on the substance. If the...
