Why do we usually use the letter "Q" to symbolize stream discharge? is it used in other sciences such as thermodynamics or fluid dynamics ... ?
thank you.
Dear Mohamed El Mahdi,
""Q" is derived from the French word "Quantité" which means "Amount" or Quantity. It was introduced by the French at the time when they dominated science (between the 18th century and the 19th century, ie. Darcy's law 1856, Poiseuille's law, 1840). The French word derives from Latin " Quantitas ".
With my best regards

Dischage means volume rate of flow. So volume means the quantity of fluid.hence the first letter of quantity Q is used for discharge
Q represents quantity. The volume rate of flow is discharge.
