# Total Discharge Head

Total discharge head is the total of the friction, pressure, and static discharge.

### Total Discharge Head Formula

\(\large{ h_d = h_{sd} + h_{pd} + h_{fd} }\)

Where:

\(\large{ h_d }\) = total discharge head

\(\large{ h_{fd} }\) = friction discharge head

\(\large{ h_{sd} }\) = static discharge head

\(\large{ h_{pd} }\) = surface discharge pressure
