| \(\large{ H }\) = system head | \(\large{ft}\) | \(\large{m}\) |
| \(\large{ h_d }\) = total discharge head | \(\large{ft}\) | \(\large{m}\) |
| \(\large{ h_s }\) = total suction head | \(\large{ft}\) | \(\large{m}\) |
System head is the difference between the total discharge head minus the total suction head.
