A modern cabin has a concrete floor that is 4.00 cm thick. A roaring | fire keeps the interior of the cabin at 21.0 °C while the air temperature below the cabin is 2.75 °c. How much heat is lost through the concrete floor in one evening (4 hrs) if the cabin measures 4.00 m by 8.00 m? A styrofoam wall (used for insulation) has a thickness of 25.4 mm. The temperature on one side of the wall is 5.50...

In cold climates, including the northern United States, a house can be built with very large windows facing south to take advantage of solar heating. Sunlight shining in during the daytime is absorbed by the floor, interior walls, and objects in the room, raising their temperature to 40.0°C. If the house is well insulated, you may model it as losing energy by heat steadily at the rate 5 550 W on a day in April when the average exterior temperature...

Thermal Storage Solar heating of a house is much more efficient if there is a way to store the thermal energy collected during the day to warm the house at night. Suppose one solar-heated home utilizes a concrete slab of area 11 m2 and 26 cm thick. If the density of concrete is 2400 kg/m3, what is the mass of the slab? The slab is exposed to sunlight and absorbs energy at a rate of 1.2 ×107J/h for 10 h....

A concrete wall of a house is 45 cm thick and has a surface area 20m x 5 m. The inside temperature of the wall is 47 °C and the outside air temperature is 14 °C. Thermal conductivity of the concrete wall is 0.8 W/mK. Calculate the heat transfer rate through the wall by conduction and its thermal resistance.
