Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.

Question

(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
