= A large wall made of 10-cm-thick solid brick (k = 0.8 W/m.K, p = 2000 kg/m, and cp 800 J/kg.K) is originally at a uniform temperature of 30C. The wall is adiabatic (well insulated) on one side as shown in the figure. The other surface is suddenly exposed to convection air flow at 10C, resulting in a heat transfer coefficient h = 40 W/m.K. (1) Determine temp. of both surfaces after 5 hr. (2) Determine Q/A removed during this period (5 hr). Adiabatic surface k, a X L Fluid To, h
