Physics · Heat Transfer
The distribution of temperature T, at a particular instant, across a large concrete wall, 1 m thick, which is heated from one side is given by the equation T = 150 − 80x + 16x2, where the distance x is in meters and T is in degrees Celsius. The thermal conductivity of the wall is 0.6 W/mK and the area of the cross section is 10 m2. The heat accumulated in unit time at this instant in the concrete wall is:
