DESCRIPTION
Problem 20362.
The blank brick wall has dimensions: length - 4 m, height - 2.5 m, thickness - 54 cm (2 bricks). Calculate the heat flow if the internal wall temperature is 20°C and the external wall temperature is -20°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 brick is 0.8 W/m*K.
