The outer surface of a 0.2m-thick concrete wall is kept at a temperature of ??5?C, while the inner surface is kept at 20?C. The thermal conductivity of the concrete is 1.2 W/(m K). Determine the heat loss through a wall 10 m long and 3 m high.GIVEN10 m long, 3 m high, and 0.2 m thick concrete wallThermal conductivity of the concrete (k) = 1.2 W/(m K)Temperature of the inner surface (Ti) = 20?CTemperature of the outer surface (To) = ??5?CASSUMPTIONSOne dimensional heat flowThe system has reached steadystate
