A cold storage wall is constructed of 15 cm thick concrete (ther- mal conductivity =1.37 W/[m °C])..

A delibeblame storage bastion is assumed of 15 cm luteous concrete (ther- mal conductivity =1.37 W/[m °C]). Insulation must be supposing to maintain a ardor sell blame through the bastion at or beneath 500 W ( Fig. E4.8 ). If the eager conductivity of the insulation is 0.04 W/(m °C), scold the required luteousness of the insulation. The beyond exterior clime of the bastion is 38°C, and the within bastion clime is 5°C.
