Ia Iuni, 2018, O se tasi o matou tagata faʻatau i Pakisitana, Karachi, latou te manaʻomia le rotameter paipa uʻamea mo le fuaina o le okesene.
O latou tulaga faigaluega e pei ona taua i lalo:
Paipa:φ70*5, Max. tafe 110m3/h，Mini.flow 10m3/h， galuega mamafa 1.3MPa, galue vevela 30 ℃, le barometric i le lotoifale 0.1MPa.
O la matou fa'atatau e pei ona taua i lalo:
①Oxygen density:
I lalo o tulaga masani:ρ20=1.331kg/m3
I lalo ole tulaga galue:ρ1=ρ20*(P1T20/PNT1Z)=1.331*{(1.3+0.1)*(27*+20)/[0.1013*(27*+30)*0.992]｝=17.93kg/ m3
②Tafe Moni:
QS=Q20ρ20/ρ
QSmax=Q20maxρ20/ρ1=110*1.331/17.93=8.166
QSmin=Q20minρ20/ρ1=10*1.331/17.93=0.742
③O le u'amea u'amea rotameter tulaga galue moni fua faatatau:
QNmax=QSmax/0.2696=8.166/0.2696=30.29
QNmin=QSmax/0.2696=0.742/0.2696=2.75
I lalo o la matou faʻataʻitaʻiga faʻaeteete, gaioiga sili ona lelei ma le faʻatonutonuina o le lelei, pe a uma ona faʻapipiʻi, e lelei atoatoa, e faʻaleleia atili ai le faʻaogaina o le tagata e faʻaaogaina, o le tulaga lelei o oloa e sili ona lauiloa e le matou tagata faʻatau.
