Kamano e pakeng tsa phepelo e futhumetseng ea lintho tsa puo ea puo ke λ = k / (ρ × c), moo K e emetse botebo, le C e emela mocheso o itseng.
1. Mohopolo oa boitšoaro bo futhumetseng
Lisebelisoa tsa Mahlaseli, ho sebelisa mekhoa ea mocheso ho bolela bokhoni ba mocheso sebakeng seo ho feta ka nako ea ho fetisoa ha yuniti. It is usually expressed by the heat flow per unit area per unit time when the temperature difference is 1K, and the unit is W/(m·K). Boholo ba mocheso li etsa hore ho be le boitšoaro bo nyonyetsi le phapanyetsano ea mocheso ea thepa eo.
2. Mokhoa oa ho bala o na le boitšoaro bo bobe
Ho kenella hoa lihlahisoa tsa puo ho amana le letsoalo, mocheso o tobileng oa boitsebiso, 'me kamano e pakeng tsa tsona ke:
Har'a bona, k e emela tšebeliso e matla ea boitsebiso, yuniti ke W / (M · k); ρ e emela botenya, yuniti ke kg / m³; C e emela mocheso o ikhethang, yuniti ke J / (KG · KG · KG · KG · KG · KG · KG · KG · KG · KG · KG · KG · KG · KG · KG · KG Mokhoa ona o re joetsa hore haeba re batla ho fokotsa boitlamo bo se nang pheko ea boitsebiso ba meqathatso, re hloka ho fokotsa maseka a mauring.
3. Lintlha tse amang moea o futhumetseng
Ho kenella ka bongata ba lintho tsa ho thekesela linthong tse ngata, joalo ka mocheso, sebopeho sa lik'hemik'hale oa boitsebiso, joalo ka bongata, litaba tsa metsi , ho na le serame le lipara tse ling tsa thepa ea lipula ea ho li-touna le tsona li tla ama tšenyo ea khatello ea matla.
