System Head

| \(\large{ H = h_d - h_s }\) (System Head) \(\large{ h_d = H + h_s }\) \(\large{ h_s = h_d - H }\) | ||
| Symbol | English | Metric | 
| \(\large{ H }\) = 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.
