Step 3: Calculate the Total Dynamic Head
Now that you have the flow rate and pressure readings, you can calculate the Total Dynamic Head using this formula:
Total Dynamic Head (TDH) = Vertical Rise + Friction Loss + Pressure
The vertical rise is the height difference between the surface of the water and the highest point of discharge, while the friction loss is the resistance of the water flowing through the pipes. Add these values to the pressure reading to get the TDH value.
