ʻO ka mea i kapaʻia i ke kahe wai liʻiliʻi e like, e like me kona inoa,ʻo ia ka mea i mālamaʻia me ka nui o ka mana liʻiliʻi.

ʻO ke kahe o ka valve ka mea kūʻai aku i keʻano o ka valve ma lalo o nā kūlana kūponoʻole. Ua hōʻikeʻiaʻo Kina e C C i ka waiwai. Ua weheweheʻiaʻo ia e like me: ke weheʻia ka valve, i ka wā e like me ka nui o ka mahana ma mua o ka nui o ka valk. No ka wai infompressibleble, ma lalo o keʻano o ka turbulence piha (i ka nui o ka helu reynolds nui, he nui no ka wai; x5 × 104 no ka ea)

ʻOʻAmelika Hui PūʻIa a me nā'āina'ē aʻe e hoʻohana i ka waiwai o C e hōʻike i ke kahe o ka kahe o ka valve. ʻIkeʻia i loko o ka internalized i, e pili ana i nā kūpeʻe e pili ana i ka uila e hoʻohana i ka waiwai e hoʻohana ai i ka nui o nā kahe o nā kahe. ʻO ke pilina pili i waena o lākou:

CV = 1 .17 C CV = 10 6 / 24V C = 10 / 28VAT

ʻO ke kahe o ke kahe o ke aniani wale nō e hilinaʻi wale i keʻano o keʻano o ka lāʻau. Ke helu nei i ka hikiʻana i ka kahe kahe o ka Valve Valve e pono ai,ʻo ia ka mea eʻikeʻia e like me keʻano o ka neʻeʻana o keʻano o ke kaheʻana.

Ma keʻano o ka nui o ka kahe liʻiliʻi,ʻoi aku ka nui o ka corcous a me ka haʻahaʻa haʻahaʻa,ʻo keʻano nui o ke kaheʻana o ka laminar a iʻole ke kaheʻana o ka laminar a me keʻano o ka laminar. I Laminawa, ke Holo nei i ka pilina o ka laina ma waena o ke kahe o ka nui ma o ke kumu o ka bales a me ka liʻiliʻi o ka malie. Ma ka hui pūʻia o ke kahe peleʻo Surpular, me ka piʻi o nā uku wikiō, inā mau ka hopena o ka nui o ka makikaʻana. I ka turbulence piha,ʻaʻole e loli ka nui o ka kahe me ka helu reynolds. Eia nō naʻe, e laweʻia ana ke koho o ka holoʻana i ka kaheʻana o ka valve i ka valve e laweʻia e nā hana kuʻuna a me nā helu helu helu. Eia nō naʻe,ʻo ka helu helu helu heluʻia mai ka waiwai maoli. E like me kaʻikepili, i ka wā e cv ma lalo o cv = 0.01 Pono e hoʻoholoʻia ka mana o ka mana maoli e like me
