A drying system works at a maximum temperature, that its internal walls are at 550C; in the external part there is air at 20C and the external heat transfer coefficient is 5.2 meET, it's internal part is cubic and measures 1m en each side, the walls have a thickness of 12 cm of a material with K=D.EWImC E-y what percentage is the heat flux reduced ifa material with K=U.O4 WEmT and 15 cm thick is placed in said system; in all external areas? What will be the average temperature at the interface between the two materials
