A 4-m-high and 6-m-wide wall consists of a long 18x30 cm2 cross section of horizontal bricks (K=0.72W/mC) separated by 3-cm-thick plaster layer (K=0.22W/mC). There are also 2-cm-thick plaster layers on each side of the wall, and a 2-cm-thick rigid form (K=0.026W/mC) on the inner side of the wall. The indoor and outdoor temperatures are 22C and -4 C, and the combined convection and radiation heat transfer coefficients on the inner and outer walls are 10W/m2C and 20W/m2C, respectively. Determine the rate of heat transfer through the wall
