PROBLEM 15.15 (WWWR) A 0.20-m-thick brick wall (k=1.3W/m•K) separated the combustion zone of a furnace from its surroundings at 25℃. For an outside wall surface temperature of 100℃‚ with a convective heat transfer coefficient of 18 W/m2•K‚ what will be the inside wall surface temperature at steady-state conditions? Solution : q k = Tw = h(Ts − Tsurrounding ) A L Tw = = h(Ts − Tsurrounding )i L k Tinside =? 0.2m Ts = 100°c (18W / m.k )(75k )(20 × 10−2 m) 1.3(W / m.k ) Tsurrounding
