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 se- conduction ukushisa :

Q/t = Izinga lokuqhuba ukushisa, k = ukuqhuba ukushisa, A = indawo enqamula ingxenye yento, T₁ = izinga lokushisa eliphezulu, T₂ = izinga lokushisa eliphansi, l = ubude bensimbi.

Izinga lokushisa = 60 ^oC.

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)

Okufunayo: Isilinganiso sesilinganiso sokuqhutshwa kokushisa

Isixazululo:

Isibalo sokuqhutshwa kokushisa:

Q/t = izinga lokuqhutshwa kokushisa, k = conductivity ezishisayo, A = indawo enqamulayo, T₂ = ukushisa okuphezulu, T₁ = 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^oC

Izinga lokushisa lokuphela kwensimbi B = 30^oC

Okufunayo: Izinga lokushisa phakathi kwezinsimbi A no-B

Isixazululo:

Isibalo sezinga lokuqhutshwa kokushisa:

Q/t = izinga lokuqhutshwa kokushisa, k = ukuhanjiswa kokushisa, A = indawo enqamulayo, T₁-T₂ = ushintsho lokushisa, l = ubude bensimbi

Izinga lokushisa eliphakathi kuka-P no-Q:

4. Izinsimbi ezimbili zinobukhulu obufanayo. Ukushisa kwensimbi II = Ukushisa okuphindwe kabili kunokushisa kwensimbi I. Uma ingxenye eyodwa yensimbi I ishiswa kanjalo T₁ = 100 ^oU-C kanye nokuphela kwensimbi II kuyashiswa ngakho-ke u-T₂ = 25 ^oC, pho izinga lokushisa lingakanani phakathi kwezinsimbi zombili.

Kwaziwa:

Ukushisa kwensimbi I = k

Ukushisa kwensimbi II = 2k

Izinga lokushisa kwelinye icala lensimbi I = 100^oC

Izinga lokushisa ekugcineni kwensimbi II = 25^oC

Okufunayo: Izinga lokushisa phakathi kwezinsimbi I kanye ne-II

Isixazululo:

Isibalo sokuqhutshwa kokushisa:

Q/t = izinga lokuqhutshwa kokushisa, k = ukuhanjiswa kokushisa, A = indawo enqamulayo, T₁-T₂ = ushintsho lokushisa, l = ubude bensimbi

Izinga lokushisa phakathi kwezinsimbi zombili:

Izinga lokushisa phakathi kwensimbi I no-II lingu-50^oC.

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

Tukuqhutshwa kokushisa kwensimbi I = k

Izinga lokushisa lokuphela kwensimbi I = 50^oC

Izinga lokushisa lokuphela kwensimbi II = 0^oC

Okufunayo: izinga lokushisa lapho kuhlangana khona izinsimbi ezimbili

Isixazululo:

Isibalo sokuqhutshwa kokudluliselwa kokushisa:

Q/t = izinga lokuqhutshwa kokushisa, k = conductivity ezishisayo, A = indawo enqamulayo, T₂ = ukushisa okuphezulu, T₁ = 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 …

Ubude bensimbi B = l

Izinga lokushisa lensimbi eyodwa A = 100^oC

Izinga lokushisa lensimbi eyodwa B = 40^oC

Okufunayo: Izinga lokushisa lapho kuhlangana khona

Isixazululo:

Isibalo sokuqhutshwa kokudluliselwa kokushisa:

Q/t = izinga lokuqhutshwa kokushisa, k = conductivity ezishisayo, A = indawo enqamulayo, T₂ = ukushisa okuphezulu, T₁ = lokushisa eliphansi, T₁-T₂ = Ushintsho lokushisa, l= ubude bensimbi

Zombili izinduku zinobukhulu obufanayo ukuze u-A akhishwe kulesi sibalo.
