There was an increase of
NPSH in the gills and muscle of tilapia fed with levels 1.04 and 1.22 mg [kg.sup.-1] when compared to the control treatment (Table 4; p = 0.0067 and p = 0.0002).
The condition of enhanced
NPSH over the south of Japan persisted from August to October.
Hepatic
NPSH levels were measured as described in [33] after sample deproteinization with 4% trichloroacetic acid.
Consider regenerative pumps for low flow/low
NPSH applications, Hydrocarbon Process (Special Report), 55-57.
NPSH level was quantified by mixing100 ul of yeast sample (treated and untreated), 1 mM of 5 dithio-bis-(2-nitrobenzoic acid) and 0.1 M reaction buffer and the reaction was completed by incubating reaction mixture at 30degC for 10 min.
Tissue
NPSH measurement and gross histopathological examination were performed as described previously (Li et al.
Vibration signals are first divided into four frequency bands, and the varying trends of vibration energy versus
NPSH are revealed.
The content of
NPSH was calculated using spectrophotometer.
Low
NPSH versions are also available for refrigeration/cooling applications, or for pumping boiling liquids or high vapour pressure liquids, with an NPSHR down to 0.5m.
The parameters of submersible pump are: flow Q = 312-315 [m.sup.3]/s, head of the pump [H.sub.p] = 5.5-4.2 m, efficiency coefficient [eta] = 0.845-0.818,
NPSH = 7.9-7.4 m.
