Total Dynamic Head :

Total Dynamic Head
Definiton :
  • It is the total equivalent height that a fluid is to be pumped and then taking into account friction losses in the pipe.
  • Total Dynamic Head in an industrial pumping system is the total amount of pressure when water is flowing in a system.
  • It is important to calculate this accurately in order to determine the correct sizing and scale of pumping equipment for your needs.
  • The combined height from the original liquid source up to the highest level to which the fluid can be pumped out of the point of discharge.
  • When a pump is lifting or pumping water, the vertical distance (in feet or meters) from the elevation of the energy grade line on the suction side of the pump to the elevation of the energy grade line on the discharge side of the pump.
Uses :
  • It is comprised of two parts: the vertical rise and friction loss.
Formula :
  • The formula for the calculation is given below.
  • Total Dynamic Head = Pumping water level from datum + Head above datum + Velocity head + Column friction lossess + Friction loss through discharge head.
  • Beside the formula this calculator works.
How to Calculate ?
  • First, Enter the Pumping Water Level from Datum. Then,
  • Second, Enter the Head above Datum. Then,
  • Third, Enter the Velocity Head. Then,
  • Fourth, Enter the Column Friction Losses. Then,
  • Fifth, Enter the Friction Loss through Discharge Head. Then,
  • Click “Calculate” to get the result and then if you want to clear values Click “Reset” in addition to clear the values.
  • Finally, follow these steps to get the result.
