Total Suction Head

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

 

Total Suction Head Formula
\(\large{ h_s =  h_{ss} + h_{ps} + h_{fs}     }\)
Units	English	Metric
\(\large{ h_s }\) = total suction head	\(\large{ft}\)	\(\large{m}\)
\(\large{ h_{fs} }\) = friction suction head	\(\large{ft}\)	\(\large{m}\)
\(\large{ h_{ss} }\) = static suction head	\(\large{ft}\)	\(\large{m}\)
\(\large{ h_{ps} }\) = surface suction pressure	\(\large{\frac{lbf}{in^2}}\)	\(\large{Pa}\)
