The right surface of wall C is completely heat insulated as shown in the figure. Inside wall C there is heat generation. The outdoor temperature is -2 ° C and the convection heat transfer coefficient is h= 20 W/m*K. The heat conduction coefficients of walls A and B and C are kA - 25 W/mK, kn - 50 W/mK, kc - 75 W/mK.
