Vertical The placed bricks were separated from each other with plaster, and the plaster thickness between the two bricks was given as 3 cm. Horizontal It was used in hard foam together with plaster between two bricks placed (in the x direction). Foam thickness 3 cm, plaster thickness is 2 cm. The indoor temperature of the wall is 20 °C, and the outdoor temperature is -10 °C. Indoor and outdoor heat transfer coefficients, respectively hi=10 W/m. °C.h2=25 W/m 2. °C. The heat transfer is unidirectional (in the x direction) and there is no radiation. is considered to be counted. Calculate the rate of heat transfer through the entire wall system. (k trick = 0.72 W/m.° C, k plaster = 0.22 W/m. C. k foam = 0.026 W/m. C)
