Product description
The panel wall made of foam concrete has dimensions: length - 5 m, height - 2.7 m, thickness - 40 cm. Calculate the heat flow if the internal temperature of the wall is 20 ° C, and the external temperature is -10 ° C. Determine the amount of heat lost through the wall in 1 s and 1 hour. Estimate the power of the heat source required to compensate for heat loss. The thermal conductivity of foam concrete is 0.25 W/m*K.
