(3) Consider a multilayer flat wall with area of A=2 m?. Assuming a steady
heat transfer and knowing that:
t;= 800°C, s,=0,2 m, 2,=25 WI(m-K);
t;= 799,4°C, Sz=0,1 m, 2=1 W/(m-K);
t= 791,9°C, S;=0,2 m, 2;=0,02 W/(m-K);
t= 40°C
calculate the results of:
a) overall thermal wall resistance
b) conductive heat transfer,
c) the temperature at the average thickness of 3rd layer
