Total Head

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

total headTotal head, abbreviated as \(h_t\), is the sum of the discharge flange and the sum of the suction flange.


Total Head formula

\(\large{ h_t = \left( h_{dg} + h_{dv} \right) - \left( h_{sg} + h_{sv} \right)   }\)   


 Units English Metric
\(\large{ h_t }\) = total head or height \(\large{ft}\) \(\large{m}\)
\(\large{ h_{dv} }\) = head velocity discharge \(\large{\frac{ft}{sec}}\) \(\large{\frac{m}{s}}\)
\(\large{ h_{sv} }\) = head velocity suction \(\large{\frac{ft}{sec}}\) \(\large{\frac{m}{s}}\)
\(\large{ h_{dg} }\) = gauge head discharge \(\large{ft}\) \(\large{m}\)
\(\large{ h_{sg} }\) = gauge head suction \(\large{ft}\) \(\large{m}\)

\(\large{ h_t = \frac{ 3960 \; WHP }{ Q }   }\)  (water horsepower)


\(\large{ h_t }\) = total head

\(\large{ Q }\) = flow rate discharge

\(\large{ WHP }\) = water horsepower
