Total Head

 

Total Head formula

\( h_t \;=\; \dfrac{ 3960 \cdot WHP }{ Q }  \)     (Total Head)

\( WHP \;=\; \dfrac{ h_t \cdot Q }{ 3960 }   \)

\( Q \;=\; \dfrac{ 3960 \cdot WHP }{ h_t }  \)

 Units English Metric
\(\large{ h_t }\) = total head or height \(\large{ft}\) \(\large{m}\)
\(\large{ Q }\) = flow rate discharge \(\large{\frac{ft^3}{sec}}\)  \(\large{\frac{m^3}{s}}\)
\(\large{ WHP }\) = water horsepower \(\large{\frac{lbf-ft}{sec}}\) \(\large{\frac{btu}{s}}\)

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