Total dynamic head (TDH) can be described as which of the following?

Explanation:
Total dynamic head represents the total energy the pump must supply to push water through the system. It accounts for the vertical lift (static head), the losses due to friction as water flows through pipes, and additional hydraulic losses from fittings, valves, and changes in direction (often including velocity head). In other words, it’s the total resistance the pump has to overcome to deliver the required flow and pressure. The other options focus on only one piece or on external pressure, which doesn’t capture the whole system energy requirement.
