Abantu, njengazo zonke izilwanyana, Siyakwazi ukulawula ubushushu bomzimba wethu ngenxa yehypothalamus, eyinxalenye yengqondo ebekwe ebuchotsheni esebenza ngendlela efanayo kwi-thermostat: xa iqondo lobushushu lendlu liphezulu kunendawo ebekiweyo, iyeka ukufudumeza ukuyihlisa.
La uvakalelo lobushushu Kukuziva ubandayo okanye ubushushu esiziva ngathi ngokudibanisa iiparameter zemozulu, phakathi kwazo ukufuma kunye nomoya. Kodwa, Ibalwa njani?
Asisayi kuba nobushushu obufanayo ngemini apho ithemometha ifundeka i-35ºC kunye nomoya wasezantsi ovuthuza ngeekhilomitha ezingama-20 ngeyure, kunolunye usuku olunobushushu obufanayo kodwa kungabikho moya. Ngoba? Kuba ujikeleze umzimba wonke umaleko womoya ugxile, obizwa ngokuba ngumda womda. Ubuncinci ngenxa yempembelelo yomoya, kokukhona ilahleko enkulu yobushushu.
Abantu banobushushu bomzimba obungama-37 degrees celcius. Nangona kunjalo, ngokuka izifundo ezahlukeneyo singathwala iidigri ezingama-55 ngokufuma okuqhelekileyo, okanye izidanga eziphezulu kwiimeko zokufuma eziphantsi. Umzekelo zii-sauna, apho iqondo lobushushu lifikelela kwi-100 degrees kwaye abantu abaya apho baphuma ngeenyawo zabo emva kweseshoni 😉.
Ngoku, ukuba ukufuma kuphezulu okanye kuphezulu kakhulu siza kuba neengxaki. Ngomswakama we-100% sinyamezele kuphela iidigri ezingama-45 kwimizuzu embalwa, njengoko umphunga wamanzi ungadibana emiphungeni.
Ulinganiswa njani umoya obandayo womoya? Ngo-2001 izazinzulu zase-Canada nase-United States zaseka i-fomyula eqinisekileyo abayifumana ngovavanyo lwebhubhoratri besebenzisa iijets zomoya kumaqondo obushushu ahlukeneyo kunye namandla omoya ebusweni kunye nokujonga ilahleko yobushushu efumaneke kulusu lwabo. Ngaba oku kulandelayo:
Tst = 13.112 + 0.6215 Ta -11.37 V0.16 + 0.3965 Ta V0.16
Ke singafumanisa ukuba ngobushushu be-10ºC kunye nomoya oyi-50km / h, isiphumo sokufudumeza kobushushu siya kuba ngu--2ºC. Ke kunomdla ngakumbi ukunikela ingqalelo kwimizimba yethu ngaphambi kwetrmometer ukwazi ukuba zeziphi iimpahla esifanele ukuzinxiba.
