(b If the tp and the bttm surfaces f the rd are nsulated, the heat transfer area f the rd s the lateral surface area f the rd, A πd. Chapter 3, Slutn C. In steady heat cnductn, the rate f heat transfer nt the wall s equal t the rate f heat transfer ut f t. Als, the temperature at any pnt n the wall remans cnstant. Therefre, the energy cntent f the wall des nt change durng steady heat cnductn. Hwever, the temperature alng the wall and thus the energy cntent f the wall wll change durng transent cnductn. Chapter 3, Slutn 3C. The temperature dstrbutn n a plane wall wll be a straght lne durng steady and ne dmensnal heat transfer wth cnstant wall thermal cnductvty. Chapter 3, Slutn 4C. The thermal resstance f a medum represents the resstance f that medum aganst heat transfer. Chapter 3, Slutn 5C. The cmbned heat transfer ceffcent represents the cmbned effects f radatn and cnvectn heat transfers n a surface, and s defned as h cmbned h cnvectn h radatn. It ffers the cnvenence f ncrpratng the effects f radatn n the cnvectn heat transfer ceffcent, and t gnre radatn n heat transfer calclatns. Chapter 3, Slutn 6C. Yes. The cnvectn resstance can be defned as the nverse f the cnvectn heat transfer ceffcent per unt surface area snce t s defned as cnv /( ha. Heat and Mass Transfer: A Practcal Apprach, 3/e, Yunus A.

The cnvectn and the radatn resstances at a surface are parallel snce bth the cnvectn and radatn heat transfers ccur smultaneusly. Chapter 3, Slutn 8C. Fr a surface f A at whch the cnvectn and radatn heat transfer ceffcents are h and h, the sngle equvalent heat transfer ceffcent s h h h when the cnv rad medum and the surrundng surfaces are at the same temperature. Then the equvalent thermal resstance wll be /( h A. eqv eqv eqv cnv rad Chapter 3, Slutn 9C. The thermal resstance netwrk asscated wth a fve-layer cmpste wall nvlves fve sngle-layer resstances cnnected n seres. Chapter 3, Slutn 0C. Once the rate f heat transfer Q & s knwn, the temperature drp acrss any layer can be determned by multplyng heat transfer rate by the thermal resstance acrss that layer, ΔT layer layer Chapter 3, Slutn C. The temperature f each surface n ths case can be determned frm ( T Ts / s Ts T ( Q & s ( T T / T T ( Q & where s s s s s the thermal resstance between the envrnment and surface. Chapter 3, Slutn C.

The wndw glass whch cnssts f tw 4 mm thck glass sheets pressed tghtly aganst each ther wll prbably have thermal cntact resstance whch serves as an addtnal thermal resstance t heat transfer thrugh wndw, and thus the heat transfer rate wll be smaller relatve t the ne whch cnssts f a sngle 8 mm thck glass sheet. Chapter 3, Slutn 4C. Cnvectn heat transfer thrugh the wall s expressed as has ( Ts T. In steady heat transfer, heat transfer rate t the wall and frm the wall are equal. Therefre at the uter surface whch has cnvectn heat transfer ceffcent three tmes that f the nner surface wll experence three tmes smaller temperature drp cmpared t the nner surface. Therefre, at the uter surface, the temperature wll be clser t the surrundng ar temperature. Chapter 3, Slutn 5C. The new desgn ntrduces the thermal resstance f the cpper layer n addtn t the thermal resstance f the alumnum whch has the same value fr bth desgns. Therefre, the new desgn wll be a prer cnductr f heat. Chapter 3, Slutn 6C. The blanket wll ntrduce addtnal resstance t heat transfer and slw dwn the heat gan f the drnk wrapped n a blanket. Therefre, the drnk left n a table wll warm up faster. Chapter 3, Slutn 36. The wall f a refrgeratr s cnstructed f fberglass nsulatn sandwched between tw layers f sheet metal. The mnmum thckness f nsulatn that needs t be used n the wall n rder t avd cndensatn n the uter surfaces s t be determned. Assumptns Heat transfer thrugh the refrgeratr walls s steady snce the temperatures f the fd cmpartment and the ktchen ar reman cnstant at the specfed values. Heat transfer s ne-dmensnal. 3 Thermal cnductvtes are cnstant. 4 Heat transfer ceffcents accunt fr the radatn effects. Heat and Mass Transfer: A Practcal Apprach, 3/e, Yunus A.

In steady peratn, the rate f heat transfer thrugh the nsulatn refrgeratr wall s cnstant, and thus heat transfer between the rm and the refrgerated space s equal t the heat transfer between the rm and the uter mm surface f the refrgeratr.
