BB02
Tha uinneag cil cuid de charbadan uidheamaichte le filament gu math tana a tha ceangailte ri uachdar a-staigh na glainne. Gus dmhlachd air an uinneig a sheachnadh, tha am filament air a theasachadh le bhith a dol seachad air sruth dealain troimhe. Gabh ris gu bheil an teas a thig bho tha am filament air a chuairteachadh gu co-ionnan tro uachdar iomlan na h-uinneige, agus mar thoradh air sin tha flux teas qo.
a. Faigh faireachdainn airson a phrifil tethachd thairis air an uinneag glainne a gabhail ris gu bheil tiugh L aige. Is e Ti tethachd an adhair taobh a-staigh a chr fada air falbh bhon uinneig agus is e an co-ifeachd gluasad teas film airson an taobh seo hi. Is e Te an tethachd rainneachd taobh a-muigh a charbaid agus is e an co-ifeachd gluasad teas airson an taobh sin e. Is e gilan teirmeach glainne k.
b. D an re de chumhachd a dh fheumar a thoirt seachad airson gach aonad gus tethachd uachdar a-staigh a chumail aig 15 C? gabh ris na luachan aithnichte a leanas: Ti =25 C; hi =10 W/m2-K; Te =-10 C; e =65 W/m2-K, k =1 W/m-K agus L =4 mm.
c. A cleachdadh luach riochdachail airson an fhor raon de dh aon uinneag mar sin, obraich a-mach na tha de chumhachd a dhth gus a chumail aig na cumhaichean a tha air an toirt seachad ann am pirt b.
