Total dynamic head
In fluid dynamics, Total Dynamic Head (TDH) is the total equivalent height that a fluid is to be pumped, taking into account friction losses in the pipe.

TDH = Static Height + Static Lift + Friction Loss
where:
Static Height is the maximum height reached by the pipe after the pump (also known as the 'discharge head').
