If the pot from previous lecture is made of other materials other than the aluminum, what will be the temperature distribution? Try stainless steel (k=15 W/m.K) and copper (385 W/m.K).
Recall: h=5 W/ m2 ?C, P=2W+2t=2(0.03+0.005)=0.07(m) AC=Wt=0.00015(m2), L=0.2(m)
Therefore, mss=(hP/kAC)1/2=12.47, mcu=2.46
Mss=?(hPkssAC) (Tb-T?)=0.028(100-25)=2.1(W)
Mcu= ?(hPkssAC) ?b=0.142(100-25)=10.66(W)
