Iphuzu eliyinhloko lomklamo we-RMS lihlanganisa izinto ezilandelayo:
- Isibalo sesayizi ye-Pipe Line kanye nomklamo
- I-Knock-out Drum / Isihlukanisi Sesihlungi / Isibalo sesayizi Sesihlukanisi Samanzi kanye nomklamo
- Isihlungi Segesi Esomile ukubala nomklamo
- Isibalo sesayizi ye-WBH
- Isilawuli, Amavavu Wokusiza kanye nokubala kosayizi we-SSV
Imigomo eyisisekelo
Ngaphambi kokuxoxa ngokwakhiwa kwe-RMS, sidinga ukuxoxa ngale mibandela elandelayo:
- I-Gauge Pressure kanye ne-Absolute Pressure
- Umthamo Ojwayelekile kanye Nomthamo Wangempela
Ukucindezela okuphelele kukalwa ngokuqhathaniswa noziro ophelele. Konke ukubala okubandakanya imithetho yegesi kudinga ingcindezi (kanye nezinga lokushisa) ukuze kube ngamayunithi aphelele.
Ukucindezela komkhathi ukucindezela emoyeni ozungezile - noma "eduze" - ebusweni bomhlaba. Ukucindezela komkhathi kuncike ekushiseni nasekuphakameni ngaphezu kwezinga lolwandle. I-Standard Atmospheric Pressure ingu-14.696 Psi (ibha engu-1.01325).
Igeji ivamise ukusetshenziselwa ukukala umehluko wengcindezi phakathi kwesistimu nomkhathi ozungezile. Lokhu kucindezela kuvame ukubizwa ngokuthi i-gauge pressure futhi kungavezwa ngokuthi:
Pg = Pa – Po
Kuphi:
Pg = I-Gauge Pressure Pa = I-Absolute Pressure
Po = Ingcindezi Yomkhathi
Ivolumu Ejwayelekileibonisa ivolumu yegesi ku-Standard Condition (izinga lokushisa elijwayelekile nesimo sokushisa), kuyilapho i-Ivolumu Yangempelaikhombisa ivolumu Kusimo Sokusebenza.
Embonini nakwezohwebo, izimo ezijwayelekile zezinga lokushisa nengcindezi ngokuvamile ziyadingeka ukuze kuchazwe izimo ezijwayelekile zokubhekisela ukuze kuvezwe umthamo wamagesi noketshezi kanye nenani elihlobene njengenani lokugeleza kwevolumu. Emashumini amahlanu kuya kwayisithupha adlule, ochwepheshe nososayensi abasebenzisa isistimu yemethrikhi yamayunithi bachaze izimo ezijwayelekile zokubhekisela zezinga lokushisa nengcindezi yokuveza amavolumu egesi njengokungu-0 °C (273.15 K;32.00 °F) kanye no-101.325 kPa (1 atm) . Ngaleyo minyaka efanayo, izimo ezijwayelekile ezisetshenziswa kakhulu abantu abasebenzisa amasistimu endabuko noma e-US kwakungu-60 °F (15.56 °C; 288.71 K) kanye no-14.696 psi (1 atm). Le ncazelo ye-Standard Condition icishe yasetshenziswa yizimboni zikawoyela negesi emhlabeni wonke. Nokho izincwadi eziningi zobuchwepheshe zivele zisho “izimo ezijwayelekile” ngaphandle kokuzicacisa, ngokuvamile okuholela ekudidekeni namaphutha.
Ifomula elandelayo (F-2) ibonisa ubudlelwano phakathi kweVolumu Ejwayelekile kanye Nomthamo Wangempela:
(F – 2)
Kuphi:
I-Vb = Ivolumu esimweni esijwayelekile, noma i-Standard Volume Vm = Ivolumu esimweni sokusebenza, noma Ivolumu Yangempela Pb = Ukucindezela okuphelele esimweni esijwayelekile
P = Ukucindezela okuphelele esimweni sokugeleza
Tb = Izinga lokushisa eliphelele esimweni esijwayelekile, KT = Izinga lokushisa eliphelele esimweni sokugeleza, K
Zb = Isici sokuminyanisa esimweni esijwayelekile Z = Isici sokuminyanisa esimweni sokugeleza
Ekwakhiweni kwe-RMS, ngokuvamile sisebenzisa izinga lokugeleza esikhundleni sevolumu. Uma kunjalo, ivolumu ye-Vm ne-Vb ingathathelwa indawo yizinga lokugeleza kwe-Qm ne-Qb.
Kuphi:
Qm = Izinga Lokugeleza Langempela. Qb = Izinga lokugeleza kokuma.
Ngokulinganisa kosayizi wamapayipi, u-Z no-Zb angabhekwa njengo-1.0.
