Muri kamena, 2018, Umwe mubakiriya bacu muri Pakisitani, Karachi, bakeneye icyuma cyitwa rotameter kugirango bapime ogisijeni.
Imikorere yabo nkuko bikurikira:
Umuyoboro ： φ70 * 5 ， Byinshi. Temba 110m3 /h，Mini.utemba 10m3 / h pressure igitutu cyakazi 1.3MPa temperature ubushyuhe bwakazi 30 ℃ pressure umuvuduko wa barometrike waho 0.1MPa.
Ibarura ryacu nkuko bikurikira:
Ubucucike bwa ogisijeni:
Muburyo busanzwe: ρ20 = 1.331kg / m3
Ukurikije akazi: ρ1 = ρ20 * (P1T20 / PNT1Z) = 1.331 * {(1.3 + 0.1) * (27 * + 20) / [0.1013 * (27 * + 30) * 0.992]｝ = 17.93kg / m3
FlowIbintu bitemba:
QS = Q20ρ20 / ρ
QSmax = Q20maxρ20 /ρ1=110*1.331 / 17.93=8.166
QSmin = Q20minρ20 /ρ1=10*1.331 / 17.93=0.742
③Icyuma cya rotameter icyuma gikora:
QNmax = QSmax /0.2696=8.166 /0.2696=30.29
QNmin = QSmax /0.2696=0.742 /0.2696=2.75
Munsi yo kubara neza, gutunganya neza no kugenzura ubuziranenge, nyuma yo kwishyiriraho, ikora neza, itezimbere imikoreshereze yanyuma yumukoresha, ibicuruzwa byamenyekanye cyane nabakiriya bacu.
