Total Head

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

\(\large{ h_t = \frac{ 3960 \; WHP }{ Q }   }\)     (Total Head)

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

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

 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 \(\large{\frac{lbf-ft}{sec}}\) \(\large{\frac{btu}{s}}\)
