Bari mu ga abin da daukar matsa lamba

A rayuwa da muke sukan fuskanci yanayi inda akwai bukatar su domin auna matsa lamba: jini, yanayi matsa lamba ko matsa iska ko gas a tube. Bari mu ga abin da irin jiki yawa. Kuma nan da nan tambaya taso: Abin da aka matsa lamba auna? Sai dai itace cewa akwai da dama iri raka'a ana amfani da wannan jiki yawa. A cikin wannan labarin, za mu bincika abin da daukar matsa lamba. Saboda haka, bari mu duba kowane daga cikin wadannan raka'a.

Hukumance gane International SI naúrar tsarin ne a matsa lamba aunawa Pascal (Pa) samu daga shi - kilopascals (kPa) da kuma megapascals (MPa). Daya Pascal ne da wadannan aboki: 1 Pa = 1 N / m ^2. Duk da haka, a sassa daban-daban amfani da raka'a matsa lamba. Alal misali, a kayyade da yi da kuma iskar gas kwarara matsa iska (a kwampreso a cikin art) za a iya amfani da dama mabanbanta raka'a.

Bari mu bincika abin da aka auna da da gas matsa lamba da kuma iska. The main naúrar ne amfani cubic mita da minti na lokaci (m ³ / min). Shi ne sau da yawa m saduwa da irin raka'a kamar yadda lita minti (l / min) ko yanayi matsa lamba (ATM), kuma a cikin Turanci kasashen iya amfani da cubic feet da minti - cubic kafar perminute, ko CFM. Bari mu dubi dangantakar da take tsakanin wadannan canji. 1 l / min yayi dace da 0,001 m ³ / min da 1 CFM daidai 28,3168 L / min, ko 0,02832 m ³ / min. Haka kuma, 1 m ³ / min ne daidai da 35.314 CFM. Sau da yawa sosai kai ga tsotsa yi ko don al'ada yanayi (1 ATM a zazzabi na 200 Celsius). A wannan yanayin, kafin mai gadin sashi sa harafin "n" wanda ke nufin da al'ada yanayin. Alal misali, 10 nm ³ / min.

Har ila yau, domin aunawa matsa lamba za a iya amfani da irin wannan raka'a: mm Hg. Art. (Ki) - millimeter na Mercury. ATM. - jiki da yanayi. al. - fasaha yanayi. mashaya. A Turanci magana kasashen iya amfani da irin wannan darajar a matsayin fam da square inch - psi (fam da square inch) .

La'akari da rabo daga cikin babban matsin lamba raka'a: 1 megapascal ne 10 mashaya ko 7500,7 milimmetrov Hg ko 9,8692 jiki atmospheres, 10,197 fasaha atmospheres da 145,04 psi.

Saboda haka mu fahimci abin da matsa lamba da aka auna a cikin fagage daban-daban na fasaha. Kuma abin da na'urorin sanya don auna jiki yawa?

Wadannan hanyoyi kuwa sune classified da irin auna matsa lamba (misali, yanayi matsa lamba, da wuce haddi ko sparse, watau, wani injin), da kuma, ba shakka, da manufa na mataki (ruwa, membrane, lantarki, spring da kuma a hade). Babban sigogi cewa faye hali a na'urar ga aunawa da iska matsa lamba - wani aji na daidaito. Akwai su da yawa irin sunadaran. Ga asali na'urar da aka fi akai-akai amfani da iska matsa lamba ji:

• aneroid hidima ga aunawa yanayi matsa lamba.
• barotermogigrometr kuma amfani da su domin auna yanayi matsa lamba.
• Liquid manometers - ana amfani da bambanci matsa lamba ji.
• analog da dijital gauges.

A takaice, mu ce da sanin matsa lamba ji raka'a iya zama da amfani a kowane zamani mutum.
