"Tête totale dynamique" ou "Charge dynamique totale"

Explanation:
For a good illustration of what this is all about, see this first website:

"Centrifugal Pump Terms

Total Dynamic Head (TDH) = Elevation(ft) + Friction(ft)"

"What is Total Dynamic Head (TDH)?

Total Dynamic Head, TDH, is the total head (another word for pressure) that the pumping system is working against.
That is, it is the total head that the pump must overcome to move water. In reality this includes friction losses through
the pump intake, in the pump column, and through the pump head. "

"Total Dynamic Head (TDH) on a self-priming pump will be the suction head plus the discharge head."
http://waterquality.deq.state.or.us/wq/wqrules/Opspump.htm

I found two different translations for this term:

"Tête Totale Dynamique: synonyme de tête totale.
Tête Totale: La différence de tête entre la sortie et l'entrée de la pompe. "
(But then, they proceed with using TDH in the text.)
http://www.cam.org/~jacobie/glos-fra.htm

"FORMULES HYDRAULIQUES
[TDH = Total Dynamic Head = charge dynamique totale]"

Just for interest:

"Tête Statique de Décharge: La différence d'élévation de la surface libre à la décharge et le centre de la pompe. Ce
terme inclut aussi la pression, s'il y en a, sur la surface libre du réservoir à la décharge. "
http://www.cam.org/~jacobie/glos-fra.htm

Hope this helps.
