Ukuhanjiswa kokushisa - izinkinga nezixazululo
1. Izinsimbi ezimbili zinobukhulu obufanayo kodwa zinezinhlobo ezahlukene. Ukushisa kwe-P = izikhathi eziphindwe kabili kunokushisa kwe-Q. Liyini izinga lokushisa phakathi kwezinsimbi ezimbili, njengoba kuboniswe esithombeni esingezansi.
Kwaziwa:
k Q = k
k P = 2k
Okufunwayo: Izinga lokushisa phakathi kwezinsimbi ezimbili
Isixazululo:
Isibalo sokuqhuba ukushisa :
Q/t = Izinga lokuqhuba ukushisa, k = ukuqhubela ukushisa, A = indawo enqamula ingxenye yento, T 1 = izinga lokushisa eliphezulu, T 2 = izinga lokushisa eliphansi, l = ubude bensimbi.
Izinga lokushisa = 60 o C.
2. Insimbi A kanye nensimbi B zinobude obufanayo kanye nendawo efanayo yesigaba. Uma ukuhanjiswa kokushisa kwensimbi A = izikhathi ezi-¼ ukuhanjiswa kokushisa kwensimbi B. Zombili izinsimbi ziyashiswa ekugcineni kwazo futhi ushintsho lokushisa kwezinsimbi zombili lufana. Isilinganiso sesilinganiso sokuhanjiswa kokushisa kwensimbi A kuya kwensimbi B.
Kwaziwa:
Ingxenye ye-A(A) = Ingxenye ye-B(A)
Ubude buka-A (l) = ubude buka-B (l)
Ukushisa kwensimbi B (k B ) = k
Ukushisa kwensimbi A (k A ) = ¼ k
Ushintsho lokushisa kwensimbi A (ΔT) = ushintsho lokushisa kwensimbi B (ΔT)
Okufunwayo: Isilinganiso sezinga lokuqhutshwa kokushisa
Isixazululo:
Isibalo sokuqhutshwa kokushisa:
Q/t = izinga lokuqhuba ukushisa , k = ukuqhuba ukushisa , A = indawo enqamulayo , T2 = izinga lokushisa eliphezulu , T1 = izinga lokushisa eliphansi , l = ubude bensimbi
3. Izinsimbi ezimbili, u-A no-B, zinobukhulu obufanayo. Ukuhanjiswa kokushisa kwensimbi u-A = 2k kanye nokuhanjiswa kokushisa kwensimbi u-B = k.
Njengoba kuboniswe esithombeni esingezansi, izinhlangothi zombili zensimbi zinezinga lokushisa elihlukile.
Lingakanani izinga lokushisa phakathi kwezinsimbi zombili?
Kwaziwa:
Izinsimbi ezimbili, u-A no-B, zinobukhulu obufanayo.
Ukushisa kwensimbi A = 2k
Ukushisa kwensimbi B = k
Izinga lokushisa lokuphela kwensimbi A = 210 o C
Izinga lokushisa lokuphela kwensimbi B = 30 o C
Okufunwayo: Izinga lokushisa eliphakathi kwensimbi u-A no-B
Isixazululo:
Isibalo sezinga lokuqhutshwa kokushisa:
Q/t = izinga lokuqhuba ukushisa , k = ukuqhutshwa kokushisa , A = indawo enqamulayo , T 1 -T 2 = ushintsho lokushisa , l = ubude bensimbi
Izinga lokushisa eliphakathi kuka-P no-Q:
4. Izinsimbi ezimbili zinobukhulu obufanayo. Ukushisa kwensimbi II = izikhathi eziphindwe kabili kunokushisa kwensimbi I. Uma ingxenye eyodwa yensimbi I ishiswa ngakho T 1 = 100 o C kanti ingxenye eyodwa yensimbi II ishiswa ngakho T 2 = 25 o C, pho izinga lokushisa lingakanani phakathi kwezinsimbi zombili.
Kwaziwa:
Ukushisa kwensimbi I = k
Ukushisa kwensimbi II = 2k
Izinga lokushisa kwelinye icala lensimbi I = 100 o C
Izinga lokushisa ekugcineni kwensimbi II = 25 o C
Okufunwayo: Izinga lokushisa phakathi kwensimbi I no-II
Isixazululo:
Isibalo sokuqhutshwa kokushisa:
Q/t = izinga lokuqhuba ukushisa , k = ukuqhutshwa kokushisa , A = indawo enqamulayo , T 1 -T 2 = ushintsho lokushisa , l = ubude bensimbi
Izinga lokushisa phakathi kwezinsimbi zombili:
Izinga lokushisa phakathi kwensimbi I no-II lingu-50 o C.
5. Izinduku zensimbi ezinobukhulu obufanayo, kodwa ezenziwe ngezinsimbi ezahlukene zihlanganisiwe njengoba kuboniswe esithombeni esingezansi. Uma ukuhanjiswa kokushisa kwensimbi I = ukuhanjiswa kokushisa okuphindwe kane kunokuhanjiswa kwensimbi II, khona-ke izinga lokushisa lapho kuhlangana khona izinsimbi ezimbili lingu ……
Kwaziwa:
Tukuqhutshwa kokushisa kwensimbi I = 4k
Ukushisa kwensimbi I = k
Izinga lokushisa lokuphela kwensimbi I = 50 o C
Izinga lokushisa lokuphela kwensimbi II = 0 o C
Okufunwayo: izinga lokushisa lapho kuhlangana khona izinsimbi ezimbili
Isixazululo:
Isibalo sokuqhutshwa kokudluliselwa kokushisa:
Q/t = izinga lokuqhuba ukushisa , k = ukuqhuba ukushisa , A = indawo enqamulayo , T2 = izinga lokushisa eliphezulu , T1 = izinga lokushisa eliphansi , T1 - T2 = Ushintsho lokushisa, l = ubude bensimbi
Zombili izinsimbi zinobukhulu obufanayo ukuze u-A no-I basuswe kulesi sibalo:
6. Isithombe esilandelayo sibonisa izinduku zensimbi ezahlukene ze-A ne-B ezixhunywe ekugcineni.
Indawo enqamulayo yezinduku zombili iyafana, kodwa ubude buka-A buphindwe kabili kunobude buka-B kanti i-coefficient yokuqhuba ukushisa ka-A iphindwe ka-B kathathu. Uma iziphetho ezikhululekile u-A no-B zibhekene namazinga okushisa ahlukene, izinga lokushisa endaweni yokuhlangana liyi …
Kwaziwa:
Tukuqhutshwa kokushisa kwensimbi A= 3k
Ukushisa kwensimbi B = k
Ubude bensimbi A = 2l
Ubude bensimbi B = l
Izinga lokushisa lensimbi eyodwa A = 100 o C
Izinga lokushisa lensimbi eyodwa B = 40 o C
Okufunwayo: Izinga lokushisa lapho kuhlangana khona imigwaqo
Isixazululo:
Isibalo sokuqhutshwa kokudluliselwa kokushisa:
Q/t = izinga lokuqhuba ukushisa , k = ukuqhuba ukushisa , A = indawo enqamulayo , T2 = izinga lokushisa eliphezulu , T1 = izinga lokushisa eliphansi , T1 - T2 = Ushintsho lokushisa, l = ubude bensimbi
Zombili izinduku zinobukhulu obufanayo ukuze u-A akhishwe kulesi sibalo.
