Mfundo yaikulu ya kapangidwe ka RMS ikuphatikizapo zinthu izi:
- Kuwerengera ndi kupanga kukula kwa mzere wa mapaipi
- Kuwerengera ndi kapangidwe ka kukula kwa Drum / Separator ya Fyuluta / Separator ya Madzi
- Kuwerengera ndi kupanga kukula kwa fyuluta ya mpweya wouma
- Kuwerengera kukula kwa WBH
- Wowongolera, Ma Vavu Othandizira ndi kuwerengera kukula kwa SSV
Mawu oyambira
Tisanakambirane za kapangidwe ka RMS, tiyenera kukambirana mawu awa:
- Kupanikizika kwa Gauge ndi Kupanikizika Kwambiri
- Voliyumu Yokhazikika ndi Voliyumu Yeniyeni
Kupanikizika konse kumayesedwa poyerekeza ndi zero yeniyeni. Kuwerengera konse kokhudzana ndi malamulo a mpweya kumafuna kuti kupanikizika (ndi kutentha) kukhale mu mayunitsi enieni.
Kupanikizika kwa mpweya ndi kupanikizika kwa mpweya wozungulira - kapena "pafupi" ndi - pamwamba pa dziko lapansi. Kupanikizika kwa mpweya kumadalira kutentha ndi kutalika pamwamba pa nyanja. Kupanikizika Kokhazikika kwa mpweya ndi 14.696 Psi (1.01325 bar).
Choyezera nthawi zambiri chimagwiritsidwa ntchito poyesa kusiyana kwa kuthamanga pakati pa dongosolo ndi mlengalenga wozungulira. Kuthamanga kumeneku nthawi zambiri kumatchedwa kuthamanga kwa gauge ndipo kungafotokozedwe motere:
Pg = Pa – Po
Kumene:
Pg = Kupanikizika kwa Gauge Pa = Kupanikizika Konse
Po = Kupanikizika kwa Mlengalenga
Voliyumu Yokhazikika imasonyeza kuchuluka kwa mpweya mu Standard Condition (kutentha koyenera ndi kutentha koyenera), pomwe Voliyumu Yeniyeni imasonyeza voliyumu mu Mkhalidwe wa Ntchito.
Mu mafakitale ndi malonda, mikhalidwe yokhazikika ya kutentha ndi kupanikizika nthawi zambiri imakhala yofunikira kuti ifotokoze mikhalidwe yokhazikika yofotokozera kuchuluka kwa mpweya ndi zakumwa ndi kuchuluka kofananako monga kuchuluka kwa volumetric flow. M'zaka makumi asanu mpaka makumi asanu ndi limodzi zapitazi, akatswiri ndi asayansi ogwiritsa ntchito njira yoyezera ya mayunitsi adafotokoza mikhalidwe yokhazikika ya kutentha ndi kupanikizika pofotokoza kuchuluka kwa mpweya kukhala 0 °C (273.15 K; 32.00 °F) ndi 101.325 kPa (1 atm). M'zaka zomwezo, mikhalidwe yokhazikika yodziwika bwino yofotokozera anthu omwe amagwiritsa ntchito machitidwe achifumu kapena aku US inali 60 °F (15.56 °C; 288.71 K) ndi 14.696 psi (1 atm). Tanthauzo ili la Standard Condition linkagwiritsidwa ntchito pafupifupi padziko lonse lapansi ndi mafakitale amafuta ndi gasi padziko lonse lapansi. Komabe, mabuku ambiri aukadaulo amangonena "mikhalidwe yokhazikika" popanda kuitchula, nthawi zambiri kumabweretsa chisokonezo ndi zolakwika.
Fomula yotsatirayi (F-2) ikuwonetsa ubale pakati pa Standard Volume ndi Real Volume:
(F - 2)
Kumene:
Vb = Voliyumu pamlingo woyenera, kapena Voliyumu Yokhazikika Vm = Voliyumu pamlingo woyenera, kapena Voliyumu Yeniyeni Pb = Kupanikizika konse pamlingo woyenera
P = Kupanikizika kotheratu pakuyenda bwino
Tb = Kutentha kotheratu pamlingo wokhazikika, KT = Kutentha kotheratu pamlingo woyenda, K
Zb = Chinthu chokakamiza pa mkhalidwe wamba Z = Chinthu chokakamiza pa mkhalidwe wa kayendedwe ka madzi
Mu kapangidwe ka RMS, nthawi zambiri timagwiritsa ntchito flow rate m'malo mwa voliyumu. Pankhaniyi, voliyumu Vm ndi Vb zitha kusinthidwa ndi flow rate Qm ndi Qb.
Kumene:
Qm = Chiŵerengero Chenicheni cha Kuyenda kwa Madzi. Qb = Chiŵerengero cha Kuyenda kwa Madzi Oyima.
Pakuyerekeza kukula kwa chitoliro, Z ndi Zb zitha kuonedwa ngati 1.0.
