Mokuna o ka ma'alahi

He aha ke'ano o ka māmā? E wehewehe i nā hi'ohi'ona o ka mea'i'o i hā'awi'ia.

'O kēia hua'ōlelo he hō'ailona nui ia o ka'aila, a me nā huahana'aila.

Nā mea o ka manawa

I ka petrochemistry hou, ua ho'ohana'ia nā'ano o ka nui o nā mea waiwai e like me kg / m3 a me g / m3. Me ke kōkua'ana o ia'ano kūpono, ua hana'ia nā helu'ana, e pili ana me ka ho'oholo'ana o ka nui o ka waiwai. Ma ke alo o ka leo, a me ka'ike nui o ka mea, hiki ke koho i ka nui o nā hua'aila.

Ke ho'oholo nei i ka waiwai

'O ka piha'ana o ka hui'ana o kahi mea ai'ole kahi ma'ema'e ka nui o ka masina i loko o ho'okahi'āpana. 'O ke ana o ka māmā i SI ka kg / m3. No ka lawe'ana i ka nui o ho'okahi mīkini kupika o ka wai i'āpala'ia, i lawe'ia ma kahi mahana o nā kūlana'ehā.

'O ke kumu,'a'ole e helu i kāna waiwai kūpono no ka waiwai a me ka pa'i'ana o nā mea, akā ka pala'a nui, e hō'ike ana i ka lakio o ka pu'upu'u o ka paila (kahi) no ka ho'oma'ema'e'ana o ka wai o ka mea like.

Wahi a ka helu helu, ua like nā koina o ka māmā a me ka māmā ma'amau, aia wale nō nā'oko'a ma ke'ano wale nō. 'A'ole kūlike ka nui o ka pilina.

Aia ma ko mākou'āina he GOST 3900 kūikawā, e like me ka mea i ho'opa'a'ia ka māmā i kahi mahana o +20 degrees Celsius.

No ka lawe'ana aku i ka'aila a me ka hua'aila, ua ho'ohana'ia nā kūlana kū'oko'a kūikawā kūikawā. Hō'ike lākou i ka ho'ohana'ana i nā hydrometers a me nā mea'enela ho'opili puke.

Ma'Amelika Huipū'ia a me'Enelani, nā ho'olaha kūlana, e like me nā kekelē, ho'okomo'ia, a me nā Bōke kūikawā Bome a me IPA. Aia ma waena o lākou he pilina, i hō'ike'ia e nā equations helu.

I kekahi mau hua'ōlelo e kuhikuhi ai, ua kāhea'ia ka inoa density d204. 'O ka'oia'i'o, ua ho'oholo'ia kēia'ano kūpono ma nā'ano like'ole e like me ka nui o ka heluna o ka ho'onui'ana o ka volumetric.

'O ka nui o ka'ona ma ke'ano he kaulike kū'oko'a he mea nui ia no nā huahana paila. Ho'ohui'ia, ho'ohana'ia kēia māhele kino i ka ho'oholo'ana i ka ho'ohui'ia'ana o ka papa hana ma o ke kānana'ana i kahi hui'ana o nā hawehe'e hau.

He aha ka mea e ho'oholo ai i ka nui

Ho'ohālikelike nā māhele o nā ana he nui kēia mea kaumaha i ka nui a me ka nui. He aha nā mea hou e hiki ai ke ho'ololi i ka waiwai o ka'ene'ena?

Ma nuʻa e loli ai i ka Nine Inch 'ano o ka constituent waiwai, fractional haku mele' ana, ka hakakino kaumaha o na constituents, i ke alo o solutes ka maʻiʻo o ka noho 'ona. Ma muli o ka hohonu a me ke anahonua, e ho'ololi ka nui o ka'aila. I loko o ka kemikalia, e ho'ohana i nā anahana o ke ana o ka nui o nā mea, e like me g / cm3.

Nā hana no ka ho'oholo'ana i ka nui

I Rusia, no ka ho'oholo'ana i ka māmā, ho'ohana'ia ke'ano isometric a me pycnometric. 'O ka lua o ka koho he loloa lō'ihi a me ka manawa hana, hā'awi ia i ka pololei o nā ana. 'O ke kumu o ka ho'ohālikelike'ana i ka nui o ka papa helu o ka'aila i'ānai'ia a hua'aila paha me ka nui o ka wai ma nā'ano like'ole. 'O ka hopena, he māmā'o ia me ka pololei o 0.0001. 'O nā pycnometers he mau kī'aha'ele'ele me ka pani'ana o ke aniani. 'O ka nui o nā moku e'ae'ia i 1, 5, 25 ml.

He aha ka hi'ona o ke'ano hydrometric? Aia kekahi kulekele kūloko i ka mea e hiki ai ke ho'oholo i ka'ene'ena o ka mea'enehu wai, a'o ka'aila maika'i i loko o ke ka'ina hana. 'O ke ala e pili ana i ka ho'ohana'ana i kahi hydrometer ke'oke'o ma +15 a +20 degrees Celsius.

'O ka hydrometer he moku'ula'ula, aia ma lalo o laila he pāpale. Pono kona wahi e kaulike. Nui ka thermometer i nā hydrometers. Hana'ia kekahi palekana kūikawā ma luna o ka mea hana,'ike'ia ka'āpana māmā. I mea e ho'onui ai i ka pololei o nā ho'oholo'ana, hiki i kekahi ke ho'ohana i ka ho'onohonoho hydrometers, me ka ho'ohana'ana i nā mahele'ē a'e ma ka pālākiō.

Ma kēia'ano e ho'oholo i ka māmā o nā mīkini'ike mālie, e ho'ohana ana i ke kaulike o ka maniscus ha'aha'a me ka kumu o ka hydrometer. Ke'ike'oe i ka nui o nā wai opaque, e heluhelu i ka pākuene hydrometer, e koho i kahi ku'ikahi me ka pahu meniscus ki'eki'e.

Me ka ho'oma'ema'e'ana o ka hydrometer, ma hope o kona ho'okumu'ia'ana, ua helu'ia nā palena ma'amau. I ka loa'a'ana o ka'oko'a mai ka mahana o + 20 degrees, e ho'oholo i ka mākau ma ke ana wela, a laila e ho'omana'o hou.

Ka helu helu'ana

I ka manawa o ke ola, ho'ohana pinepine nā kānaka i nā'ōlelo like: "mālamalama e like me ka ea", "kaumaha e like me ke alaka'i". Ma kēia'ano,'a'ohe paha lākou e no'ono'o inā loa'a iā lākou kekahi mana'o.

Ma ke papa'ōnaehana physics, ua hā'awi'ia nā keiki i ka helu'ana i ka helu'ana o nā mea'ilima: ka nui, ka nui, ka leo. Eia kekahi la'ana, e mana'o'ia e helu i ka nui o nā pale keleawe a me nā'aleka e like me ke'ano o ka pahu. No ka pa'i'ana i kēia hana, pono'oe i kahi hō'ailona e like me ka nui. 'O ka māmā o ke kila,'o ka nui o ka pahu e loa'a.

Pehea e ana ai i ka nui o nā'āpana po'o i nā mea like'ole? 'O ka mea mua, pono'oe e ho'oholo i ke ki'eki'e, ka laulā, ka lō'ihi o kēlā me kēia mea, e helu i ka leo e nā mea i loa'a. Oe ke laila, ke hoʻohana i ka une lōhai paona kūkulu o ka paona. No ka ho'oholo'ana i ka māmā, pono pono ke'ike i ka ratio o ka nui-a-volume o ka mea.

Ka Hopena

He aha ka wela? He He physical nui i characterizes he mau waiwai. Hō'ike'ia'o ia ka lākiō o ka nui o ka waiwai i ka leo. Kēia aiao ua denoted ma ka palapala (po-), i ke kumu o ka mokuna o ke ana i loko o International Si mea kg / m3. Hō'ike ia i ka waiwai pono'ī,'a'ole ia i hilina'i i ka nui a i'ole ka nui o ka helu mua. Ke ho'onui'ia ka nui o ka hu'u a mea'aila paha, e emi iho ka nui o ka leo, e mau ana ka pa'a.
