Kia kite a he aha te pēhanga i whanganga ano

I roto i te ora maha e fehangahangai tatou ki ngā āhuatanga i reira i reira he he hiahia ki te ine i te pēhanga: toto, pēhanga kōhauhau ranei hau kōpeke ranei hau i roto i te ngongo. Kia kite a he aha te ahua o te rahinga tinana. Na tonu whakatika te pātai: He aha te whanganga i te pēhanga? Huri i te reira i roto i taua i reira e kua tono e rave rahi ngā momo o ngā waeine ki tenei rahinga tinana. I roto i tenei tuhinga, ka titiro tatou ki ta te pēhanga i whanganga. Na, kia whai whakaaro a ia o enei wae.

Mana mohio pūnaha wae International SI ko te pēhanga whanganga Pascal (Pa) i takea mai i reira - kilopascals (kPa) me megapascals (MPa). Ko tētahi Pascal Ko te pā ana e whai ake nei: 1 Pa = 1 N / m ^2. Heoi, te whakamahi i roto i ngā rāngai rerekē ngā wae o te pēhanga. Hei tauira, i roto i te whakatau i te mahi me te hau rere o te hau kōpeke (he compressor i roto i te toi) Ka taea te whakamahi te maha ngā wae tino rerekē.

Kia tātari tatou he aha te whanganga e te pēhanga hau me te hau. tono te kōwae matua te mita pūtoru ia meneti o te wā (m ³ / min). Ko maha taea ki te whakatau me te taua wae rite rita ia meneti (l / min) pēhanga kōhauhau (atm) ranei, me i roto i nga whenua Ingarihi-korero e taea te whakamahi i waewae pūtoru ia meneti - perminute waewae pūtoru, CFM ranei. Kia titiro a ki te hononga i waenganui i enei taurangi. 1 l / hāngai min ki 0,001 m ³ / min me ōrite 1 CFM 28,3168 L / min, 0,02832 m ³ / min ranei. Nä, he rite ki te 35.314 CFM 1 m ³ / min. Tino maha arahi ki te mahi momi mo te tikanga noa (1 atm i te pāmahana o te 200 degrees) ranei. I roto i tenei take, i mua i te kōwae hoatu reta "n" e te tikanga te huru noa. Hei tauira, 10 Numbers ³ / min.

Ano hoki te pēhanga ruri e taea te tono pera wae: mm HG. Art. (Torr) - mirimita o konuoi; atm. - huru tinana; al. - huru hangarau; pae. I roto i te reo Ingarihi whenua korero taea te whakamahi i te uara pērā i pauna ia īnihi tapawha - PSI (pauna ia īnihi tapawha) .

A feruri i te ōwehenga o te wae pēhanga matua: 1 megapascal ko 10 pae ranei 7500,7 milimmetrov HG ranei 9,8692 atmospheres tinana, 10,197 atmospheres hangarau, me te 145,04 PSI.

Na matau tatou ki ta whanganga te pēhanga i roto i te wāhi rerekē o te hangarau. Na te aha i hanga nga whakaaro ki te ine i ngā rahinga tinana?

E whakarōpūtia ēnei tikanga i te momo o te pēhanga whanganga (hei tauira, te pēhanga kōhauhau, i te taikaha korekore ranei, arā, he mārua), me, o te akoranga, te parau tumu o te mahi (wai, membrane, hiko, puna, me te ngā). Ko te tawhā matua e tohu he pūrere mō te ine i te pēhanga hau - he piha o te tika. He maha tikanga pera. Here te pūrere taketake e kua tino pinepine whakamahia i roto i te ine pēhanga hau:

• aneroid tavini hoki whanganga te pēhanga kōhauhau;
• whakamahia hoki barotermogigrometr ki te ine i te pēhanga kōhauhau;
• manometers wai - e whakamahia mō te ine pēhanga pārōnaki;
• tairitenga me gauges mamati.

Hei whakarāpopoto, mea tatou e kia te matauranga o wae inenga pēhanga whai hua ki tetahi tangata hou.
