Total Discharge Head
Total discharge head. abbreviated as \(h_d\), also called total head or total dynamic head, is used in fluid mechanics and hydraulic engineering to describe the total energy per unit weight of fluid at any point in a hydraulic system. It represents the sum of different components of head, each contributing to the total energy of the fluid.

\(\large{ h_{fd} }\) = friction discharge head | \(\large{ft}\) | \(\large{m}\) |
\(\large{ h_{sd} }\) = static discharge head | \(\large{ft}\) | \(\large{m}\) |
\(\large{ h_{pd} }\) = surface discharge pressure | \(\large{\frac{lbf}{in^2}}\) | \(\large{Pa}\) |
