NPSH available
Net Positive Suction Head available at the pump inlet, compared to the pump's NPSH-required. Suction-line friction loss is computed from your pipe geometry.
Computed friction loss
0.072m
= 0.236 ft
Over 6 m total length (incl. fittings).
Suction velocity
0.995m/s
= 3.26 ft/s
Within the ≤ 1.5 m/s suction-line target.
NPSH available
11.1m
= 36.4 ft
Margin vs required
+8.1m
= +26.6 ft
8.1 m above NPSH-required. Safe operating margin.
