Which formula would be used to calculate the Total Dynamic Head (TDH) of a pump?

Total Dynamic Head (TDH) is a crucial concept in pump systems, representing the total height that a pump needs to overcome in order to move a fluid. The calculation of TDH incorporates various head components, which account for different factors that influence the performance of the pump.

The correct formula for TDH includes the following components:

• Hs: Static head, which is the vertical distance the fluid must be lifted from its source to the discharge point.

• Hp: Pump head, which reflects the energy added to the fluid by the pump.

• Hf: Friction head, representing the energy loss due to friction as the fluid moves through the piping system.

• Hv: Velocity head, which accounts for the kinetic energy of the fluid flowing through the system.

The formula that correctly sums these components is TDH = Hs + Hp + Hf + Hv. This comprehensive equation ensures that all relevant factors contributing to the necessary pressure and energy for effective fluid transport are considered. Thus, it provides an accurate measure of the total dynamic head required for the pump to function efficiently in a given application.

Other options do not correctly account for all the factors or mix components in a way that does not accurately reflect the requirements of a pump system, leading
