Itsika yakajairika kushandisa mhepo inotonhodza huku munguva yezhizha inopisa. Pakuchengeta mazai akawanda, mhepo inovhuvhuta nekukurumidza.chikwere chehukuinofanira kusvika 3m/s, uye kumhanya kwemhepo muimba yehuku munzvimbo dzinopisa zvakanyanya uye dzine hunyoro hwakawanda kunofanira kusvika kupfuura 4m/s kuitira kuti pave ne "mhepo inotonhodza" zviri nani.
"Mhedzisiro yekutonhodza mhepo" inonyanya kureva kumhanya kwemhepo kuderedza tembiricha yemuviri yehuku.
Kumhanya kwemhepo kunogona kukanganisa sei tembiricha yemuviri yehuku?
"Zvichienderana neongororo yakaitwa neYunivhesiti yeGeorgia, kumhanya kwemhepo kwakawedzera kubva pa0m/s kusvika pa2.54m/s. Tembiricha yemuviri yehuku ichadzikira neanopfuura madhigirii matanhatu."°C.”
Kuti ndiwane kumhanya kwemhepo kwakanyanya, tsika yangu yakajairika ndeyekuita kutiimba yehukudenga, deredza kureba kwechikwere chehuku, kana kubva pamusoro pechikwere chehuku uchitevedza denga retriangular wakadzika pasi pese paunoda kuisa chivharo chemhepo kana keteni remhepo kuderedza nzvimbo yechikwere chehuku kuti uwedzere kumhanya kwemhepo muchikwere.
Sei uchiita izvi, kunyanya nekuti kumhanya kwemhepo kwakabatana zvakanyanya nenzvimbo inoyambuka miganhu yenzvimbo iyichikwere chehuku.
Kuverengerwa kwekumhanya kwemhepo muchikwere chehuku chinofefeterwa kwenguva refu: kumhanya kwemhepo = vhoriyamu yekufema / nzvimbo yechikamu chechikwere
Zviri pachena kubva mufomura iyi kuti kuwedzera kumhanya kwemhepo mu coop, kuwedzera kufefetera kwe coop, kureva kuwedzera huwandu hwemafeni anodzivirira kumanikidzwa, kana kuderedza nzvimbo ye coop.
Kuwedzera mafeni zvinoreva kuwedzera mitengo, kuwedzera kushandiswa kwemagetsi, kuwedzera mari yekugadzirisa, uye pakupedzisira kuwedzera mari yakawanda yekushanda kubhizinesi.
Zvadaro, kuwedzera kumhanya kwemhepo kunofanirwa kufungwa nezvako kubva pakuderedza nzvimbo yepakati penzvimbo.chikwere chehukuPazasi tinonzwisisa shanduko dzechikwere chehuku dzisati dzawedzera uye dzapera nekuverenga kwakananga.
Semuenzaniso: chikwere chehuku chine upamhi hwemamita gumi nemaviri, kureba kwemamita zana, madziro emativi echikwere akareba 2.4m, pakati pechikwere (chepamusoro-soro) i4.8m, chikwere chakaiswa nemafeni gumi nehafu, simba rekufema refeni yega yega pa -50 Pa i31000m³/h.
Saka kumhanya kwemhepo kwehuku kunofanira kunge kuri: kumhanya kwemhepo = vhoriyamu yekufema / nzvimbo yepakati = 31000 / 3600× 10 / [12]× (4.8 + 2.4) / 2] = 86.1/43.2 = 1.99m/s
Kana tikaisa jira redenga kana remhepo muchikwere chehuku, zvekuti kukwirira kwepamusoro pechikwere kana kumucheto kwepasi kwejira kubva pasi kuri 3.6m, uye kukwirira kwemativi ese echikwere kusachinja, kumhanya kwemhepo kuri = 31000/3600×10/[12]×(3.6+2.4)/2]=86.1/36=2.39m/s
Saka, kana paine mafeni akafanana, nekuderedza nzvimbo yehuku iri pakati penzvimbo inogona kuwedzera kumhanya kwemhepo zvichibva pa 0.4m/s yekutanga, kureva kuti, kushanda zvakanaka kwakawedzera ne20%, shanduko dzekukurumidza kwemhepo dzinokonzerwa nekutonhodza kwemhepo dzakasiyanawo, musiyano uripo pakati pemhepo mbiri dzinotonhodza unoenderana nekupisa kweanenge madhigirii maviri.℃, kana tembiricha yakakwira zvakanyanya, mutsauko wetembiricha we2℃zvakakwana kukonzera kukuvara kukuru kune huku.
