Total head, N.P.S.H. and other calculations…19
Calculation results (method 1 – pressure at the control valve inlet)
The sign in the second column follows the signs of the terms in equation [16].
Component Sign (ft fluid) Results
Total head + ∆H P 97.34
Pipe friction head loss - ∆H FP1-7 16.2
Fittings friction head loss - ∆H FF1-7 10.5
Equipment friction head loss - ∆H EQ1-7 18.85
Check valve head loss - ∆H CHECK 1.65
Total static head + z 1 – z 7 - 43
Velocity head difference + v 2 1/2g – v 2 7 /2g - 1.62
Tank pressure head + H 1 0
Pressure head at the control valve (ft fluid) = H 7 5.52
Pressure at the control valve (psig) = p 7 2.34
