Problem 2. Two walls of cold storage plant are composed of an insulating material (k=0.25 kJ/hr-m-°C), 100 mm thick at the outer layer and material (k=3.5 kJ/hr-m-°C), 15 cm thick at inner layer. If the surface temperature at the cold side is 30°C and hot side is 250°C, find the heat transmitted per square meter.
