Yakakosha poindi yeRMS dhizaini inosanganisira zvinotevera zvinhu:
- Pipe Line saizi kuverenga uye dhizaini
- Knock-out Drum / Filter Separator / Liquid Separator saizi yekuverenga uye dhizaini
- Dry Gasi Sefa saizi yekuverenga uye dhizaini
- WBH saizi kuverenga
- Regulator, Relief Mavharuvhu uye SSV saizi yekuverenga
Basic terms
Tisati takurukura dhizaini yeRMS, tinoda kukurukura mazwi anotevera:
- Gauge Pressure uye Absolute Pressure
- Standard Vhoriyamu uye Chaiyo Vhoriyamu
Mhedziso yekumanikidza inoyerwa zvichienderana neabsolute zero. Kuverenga kwese kunosanganisira mitemo yegesi kunoda kudzvanywa (uye tembiricha) kuve muzvikamu zvakakwana.
Atmospheric pressure (atmospheric pressure) idzvinyiriro iri mumhepo yakatenderedza pa- kana kuti “pedyo” nepamusoro penyika. Kutsikirira kwemuchadenga kunotsamira pakupisa nekukwirira pamusoro pegungwa. Iyo Standard Atmospheric Pressure ndeye 14.696 Psi (1.01325 bar).
Chiyero chinowanzo shandiswa kuyera musiyano wekumanikidzwa pakati pehurongwa nemhepo yakatenderedza. Iyi dzvinyiriro inowanzonzi gauge pressure uye inogona kuratidzwa se:
Pg = Pa – Po
Kupi:
Pg = Gauge Pressure Pa = Absolute Pressure
Po = Atmospheric Pressure
Standard Volumeinoratidza huwandu hwegasi muStandard Condition (yakajairika tembiricha uye tembiricha mamiriro), nepo iyoBhuku Rechokwadiinoratidza vhoriyamu muOperation Condition.
Muindasitiri nekutengeserana, mamiriro akajairwa etembiricha uye kudzvanywa anowanzodikanwa kutsanangura akajairwa mareferensi mamiriro ekutaura mavhoriyamu emagasi uye zvinwiwa uye huwandu hwakabatana senge chiyero chekuyerera kwevhoriyamu. Mumakumi mashanu kusvika kumakumi matanhatu emakore apfuura, nyanzvi nesainzi vachishandisa metric system yemayuniti vakatsanangura mamiriro akajairwa etembiricha uye kumanikidza kuratidza mavhoriyamu egasi kunge 0 ° C (273.15 K; 32.00 ° F) uye 101.325 kPa (1 atm) . Mukati memakore mamwe chete iwayo, aiwanzo shandiswa akajairwa mareferensi mamiriro evanhu vanoshandisa humambo kana US tsika masisitimu aive 60 °F (15.56 °C; 288.71 K) uye 14.696 psi (1 atm). Iyi tsananguro yeStandard Condition yakada kushandiswa pasi rose nemaindasitiri emafuta negasi pasi rese. Zvakadaro mabhuku mazhinji ehunyanzvi anongotaura "zvakajairwa mamiriro" pasina kuatsanangura, kazhinji zvichitungamira mukuvhiringidzika uye kukanganisa.
Iyi inotevera fomula (F-2) inoratidza hukama pakati peStandard Vhoriyamu neChaiyo Vhoriyamu:
(F – 2)
Kupi:
Vb = Vhoriyamu pane yakajairika mamiriro, kana Standard Volume Vm = Vhoriyamu pamamiriro ekushanda, kana Actual Vhoriyamu Pb = Absolute kumanikidzwa pane yakajairika mamiriro
P = Absolute pressure panguva yekuyerera
Tb = Tembiricha yakakwana pane yakajairwa mamiriro, KT = Tembiricha yakakwana pakuyerera, K
Zb = Compressibility factor at Standard condition Z = Compressibility factor at flow condition
MuRMS dhizaini, kazhinji isu tinoshandisa chiyero chekuyerera pane vhoriyamu. Muchiitiko ichocho, vhoriyamu Vm neVb inogona kutsiviwa nekuyerera kweQm neQb.
Kupi:
Qm = Chaiyo Flow Rate. Qb = Stand Flow Rate.
Kuyeresa pombi saizi, Z uye Zb inogona kutariswa se 1.0.
