Question:

There are a number of ways for capturing solar energy for home heating. The simplest of these is the heat-storing wall. It is a thick wall, the outer surface of which is heated by exposure to direct sun-shine during the day, and from which heat is extracted by night by blowing air over its inner surface. You are asked to select the optimal wall material that will maximize the thermal energy captured by the wall. The wall thickness is limited to 0.5 m. The sun heats the wall during the day, and heat is extracted from it at night. The heat diffusion time through the wall must be about 12 hours. Heat diffusion time through the wall, t = 12 hrs Wall Thickness, w less than or equal to 0.5 m Choice of Material Wall thickness, w
