Total Dynamic Head Calculator

Formula

The formula to calculate the Total Dynamic Head is:

\[ TDH = PH + FLH + EH \]

Where:

Total Dynamic Head (TDH) is the total head loss that a pump must overcome in order to move and pump water. The total head loss has three components:

Elevation Head: The amount of head/pressure the pump needs to overcome due to the elevation of the system.
Pressure Head: The amount of head the pump needs to overcome due to pressure.
Friction Loss Head: The head created due to friction of the water flow in the pipes.

Let's say you have a pressure head (PH) of 10 ft, a friction head loss (FLH) of 5 ft, and an elevation head (EH) of 15 ft. Using the formula:

\[ TDH = 10 + 5 + 15 = 30 \, \text{ft} \]

So, the total dynamic head (TDH) would be 30 ft.
