Phetisetso ea mocheso - mathata le litharollo

Phetisetso ea mocheso - mathata le litharollo

1. Litšepe tse peli li na le boholo bo tšoanang empa li na le mefuta e fapaneng. Phetisetso ea mocheso ea P = makhetlo a 2 a phetisetso ea mocheso ea Q. Ke eng mocheso pakeng tsa litšepe tse peli, joalo ka ha ho bontšitsoe setšoantšong se ka tlase.

Tse tsejoang:

k_Q = k

k_P = 2k

Oa Batla: Mocheso pakeng tsa litšepe tse peli

Tharollo:

Tekanyo ea ho tsamaisa mocheso :

Q/t = Sekgahla sa ho tsamaisa mocheso, k = ho tsamaisa mocheso, A = sebaka sa karolo e tshekaletseng ya ntho, T₁ = mocheso o phahameng, T₂ = mocheso o tlase, l = bolelele ba tšepe.

Mocheso = 60 ^oC.

2. Tšepe A le tšepe B li na le bolelele bo tšoanang le sebaka se tšoanang sa karolo e tšekaletseng. Haeba phetisetso ea mocheso ea tšepe A = makhetlo a ¼ phetisetso ea mocheso ea tšepe B. Litšepe ka bobeli li futhumatsoa qetellong ea tsona 'me phetoho ea mocheso oa litšepe ka bobeli e tšoana. Karolelano ea sekhahla sa phetisetso ea mocheso ea tšepe A ho tšepe B.

Tse tsejoang:

Karolo e tšekaletseng ea A(A) = Karolo e tšekaletseng ea B(A)

Bolelele ba A (l) = bolelele ba B (l)

Ho khanna ha mocheso oa tšepe B (k)_B) = k

Ho khanna ha mocheso oa tšepe A (k)_A) = ¼ k

Phetoho mochesong oa tšepe A (ΔT) = phetoho mochesong oa tšepe B (ΔT)

Oa Batla: Karolelano ea sekhahla sa ho khanna ha mocheso

Tharollo:

Tekanyo ea ho khanna mocheso:

Q/t = sekhahla sa ho khanna mocheso, k = conductivity e chesang, A = sebaka se nang le karolo e tšekaletseng, T₂ = mocheso o phahameng, T₁ = mocheso o tlase, l = bolelele ba tšepe

3. Litšepe tse peli, A le B, li na le boholo bo lekanang. Ho tsamaisoa ha mocheso ha tšepe A = 2k le ho tsamaisoa ha mocheso ha tšepe B = k.

Jwalo ka ha ho bontshitswe setshwantshong se ka tlase, dipheletso tsa ditshipi ka bobedi di na le dithempereichara tse fapaneng.

Thempereichara e pakeng tsa litšepe tsena ka bobeli ke efe?

Tse tsejoang:

Litšepe tse peli, A le B, li na le boholo bo lekanang.

Ho khanna ha tšepe ka mocheso A = 2k

Ho khanna ha tšepe ka mocheso B = k

Mocheso oa pheletso e 'ngoe ea tšepe A = 210^oC

Mocheso oa pheletso e 'ngoe ea tšepe B = 30^oC

Oa Batla: Mocheso o pakeng tsa litšepe A le B

Tharollo:

Tekanyo ea sekhahla sa ho khanna mocheso:

Q/t = sekhahla sa ho khanna mocheso, k = conductivity ea mocheso, A = sebaka se nang le karolo e tšekaletseng, T₁-T₂ = phetoho ea mocheso, l = bolelele ba tšepe

Mocheso o pakeng tsa P le Q:

4. Litšepe tse peli li na le boholo bo lekanang. Ho tsamaisa mocheso ha tšepe II = ho tsamaisa mocheso ha tšepe I ka makhetlo a 2. Haeba ntlha e 'ngoe ea tšepe I e futhumatsoa kahoo T₁ = 100 ^oC le pheletso e 'ngoe ea tšepe II lia futhumatsoa kahoo T₂ = 25 ^oC, joale mocheso o pakeng tsa litšepe tsena ka bobeli ke ofe.

Tse tsejoang:

Ho khanna mocheso ha tšepe I = k

Ho khanna ha mocheso oa tšepe II = 2k

Mocheso pheletsong e 'ngoe ea tšepe I = 100^oC

Mocheso pheletsong e 'ngoe ea tšepe II = 25^oC

Oa Batla: Mocheso pakeng tsa litšepe tsa I le II

Tharollo:

Tekanyo ea ho khanna mocheso:

Q/t = sekhahla sa ho khanna mocheso, k = conductivity ea mocheso, A = sebaka se nang le karolo e tšekaletseng, T₁-T₂ = phetoho ea mocheso, l = bolelele ba tšepe

Mocheso pakeng tsa litšepe ka bobeli:

Mocheso o pakeng tsa tšepe I le II ke 50^oC.

5. Lithupa tsa tšepe tsa boholo bo lekanang, empa li entsoe ka litšepe tse fapaneng li kopantsoe joalo ka ha ho bontšitsoe setšoantšong se ka tlase. Haeba ho khanna ha mocheso oa tšepe I = makhetlo a 4 ho feta ho khanna ha tšepe II, joale mocheso o kopanang le litšepe tse peli ke ……

Tse tsejoang:

Tho khanna ha mocheso oa tšepe I = 4k

Tho khanna ha mocheso oa tšepe I = k

Mocheso oa pheletso e 'ngoe ea tšepe I = 50^oC

Mocheso oa pheletso e 'ngoe ea tšepe II = 0^oC

Oa Batla: mocheso moo litšepe tse peli li kopanang teng

Tharollo:

Tekanyo ea phetisetso ea mocheso:

Q/t = sekhahla sa ho khanna mocheso, k = conductivity e chesang, A = sebaka se nang le karolo e tšekaletseng, T₂ = mocheso o phahameng, T₁ = mocheso o tlase, T₁-T₂ = Phetoho ea mocheso, l = bolelele ba tšepe

Litšepe ka bobeli li na le boholo bo lekanang hoo A le I li tlosoang ho equation:

6. Setšoantšo se latelang se bontša lithupa tse fapaneng tsa tšepe tsa A le B tse hokahaneng pheletsong e 'ngoe.

Sebaka sa lithupa ka bobeli se tšoana, empa bolelele ba A bo habeli ho feta bolelele ba B 'me coefficient ea ho tsamaisa mocheso oa A ke makhetlo a 3 ho B. Haeba lipheletso tse lokolohileng tsa A le B li le tlas'a mocheso o fapaneng, mocheso o kopaneng ke ...

Tse tsejoang:

Tho khanna ha tšepe ka mocheso A= 3k

Tho khanna ha tšepe ka mocheso B = k

Bolelele ba tšepe A = 2l

Bolelele ba tšepe B = l

Mocheso oa tšepe e le 'ngoe A = 100^oC

Mocheso oa tšepe e le 'ngoe B = 40^oC

Oa Batla: Mocheso moo ho kopanang teng

Tharollo:

Tekanyo ea phetisetso ea mocheso:

Q/t = sekhahla sa ho khanna mocheso, k = conductivity e chesang, A = sebaka se nang le karolo e tšekaletseng, T₂ = mocheso o phahameng, T₁ = mocheso o tlase, T₁-T₂ = Phetoho ea mocheso, l = bolelele ba tšepe

Lithupa tsena ka bobeli li na le boholo bo lekanang hoo A e tlosoang ho equation.
