3- A building wall consists of 25 cm concrete (K= 1.75 W/m.K) and 1.9 cm plaster (K= 87 W/m.K) on the inside surface. The outside temperature is -18°C, while the room is held at 23.5°C DBT and 16.8°C WBT. (a) What is the temperature on the inside wall surface. (b) Will the moisture condense on the wall. (c) How many layers of 1.25 cm thick fiber-board insulation (K= 0.048 W/m.K) should be applied on the inside wall surface to prevent moisture to condense on it.
