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

 

Total Head formula

\(\large{ h_t = \frac{ 3960 \; WHP }{ Q }   }\) 
 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 \(\large{\frac{lbf-ft}{sec}}\) \(\large{\frac{btu}{s}}\)
  • 1 horsepower = 3960 gal/min/foot
