He aha ka jet nozzle?- Ke alakaʻi neiʻo Kina i nā kiʻi nozzle nozzle

'Ōlelo Jet nozzle he mea koʻikoʻi koʻikoʻi i ka prosulsion, mana pā'āʻu, ʻO ka hanaʻoihanaʻenehana, a me ka halihali.

ʻO kāna core core e hoʻohuli i ka ikaika a me ka ikaika o ka ikehu i loko o ke kahe nui, E hāʻawi ana i ka hana, kuhikuhi i ka manawa, a iʻole ka hoʻokeleʻana.

ʻOiaiʻo kāna hana a me keʻanoʻo Orodynamic a me keʻano hana, ʻO kaʻike kūleʻa kūleʻa o kahi not over nozzle hilinaʻi nui ʻO nāʻepekema, Nā hana hana-lāʻau, E hana ana i nā koho koho.

1. He aha kahi jet nozzle?

A Jet nozzle he meaʻenehana kūikawā e hoʻohuli ai ke kaumaha a me ka ikehu o kahi wai (hau a wai paha) i loko o kuhikuhi i ka iketicic ikehu, e hana ana i kahi jet.

ʻAʻole hiki i nā kelepona maʻalahi a iʻole nā nozzles i hoʻohanaʻia no nā noi haʻahaʻa haʻahaʻa, Hoʻolālāʻiaʻo Jet nozzles e hoʻokele wikiwiki-wikiwiki, ka mahana kiʻekiʻe, a me nā kahe nui, e hana ana iā lākou i ka prosulsion, mana pā'āʻu, a me ka hana holomua.

Nā hiʻohiʻona koʻikoʻi

• Ka hoʻololiʻana: 'Ōlelo Nzzle hoʻololi i ke kaomi stagnation a me ka hoihoi mai kahi kumu wai (E.g., ʻO ka Chamber Chamber, ka hoʻopiha, a iʻole pump) i loko o ka wikiwiki.
• Kaho kahe: E kuhikuhi ana ia JET ke kuhikuhi, huhalau, A me ka hoʻonuiʻana; i ka propullision, Ua unuhi kēia i ka nui.
