(5-2) The shown firm stope wall is of 300 mm total thickness, 10 m long and 3 m high. It is finished on the inside with 30 mm of cement plaster (p 2,000 kg/m) and 50 mm of polystyrene board (p=30 kg/m). The concrete layer thickness is 150 mm (p= 2,300 kg/m). The inside and outside air temperatures are 20 and -2"C, respectively. The wind speed is 10 %3D %3D m/s. Calculate the followings: (a) Overall heat transfer coefficient of the wall.
