Steady-state heat flow through hollow clay bricks
Clay bricks are commonly used for building wall. One of the functions of a wall is to create a habitable internal environment, such as enabling internal temperature to be controlled at a human comfort level (?24�C) which is lower than the outside temperature for hot and humid climate countries. Thus...
