Consider a house that is approximated as a cube that is 8 m on a side and has no windows. The house loses heat from the four walls and the roof. For an inside temperature of 20°C and an outside temperature of –20°C, it is desired to keep the total heat loss less than 5 kW. What is the minimum Rsj-value that is required for the walls and roof?

When the temperature was 3 deg. C, the distance from E to F was measured using a steel tape that has a standard length of 100m at 20 deg. C with a coefficient of thermal expansion of 0.0000116 / deg. C. If the correct distance from E to F is 836.5 m, what is the measured distance in meters?
A 50-L electrical radiator containing heating oil is placed in a 50-m³ room. Both the room and the oil in the radiator are initially at 5°C. The radiator with a rating of 3 kW is now turned on. At the same time, heat is lost from the room at an average rate of 0.3 kJ/s. After some time, the average temperature is measured to be 20°C for the air in the room, and 60°C for the oil in the radiator. Taking the density and the specific heat of the oil to be 950kg/m³ and 2.2kJ/(kg °C), respectively, determine how long the heater is kept on. Assume the room is well-sealed so that there are no air leaks.
An insulated steam pipe having outside diameter of 3 cm is to be covered with two layers of insulation each having a thickness of 2.5 cm. the thermal conductivity of one material is 5 times that of the other assuming that the steam pipe surface temperature and outer air temperature remain fixed . how much change in heat transfer take place if the better insulating material is next to the pipe than it is on outer side?
A line was measured to be 412 m using a 30-m tape, which is of standard length at a temperature of 20 deg.C. During measurement, the temperature was 52 deg.C. If the coefficient of thermal expansion of the tape material is 0.0000116 m/m deg.C, calculate the correct length of the line.

A 2 x 2 m flat plate solar collector for domestic hot water heating is shown in the figure. The incident solar radiation on the glass cover, which transmits 90% of the incident flux, is 750 W/m2. Water flows through the tubes soldered to the backside of the absorber plate, entering at a temperature of 25°C. The temperature of the glass cover is 27°C, and it radiates heat with an emissivity of 0.92 to the sky at –50°C. Additionally, the glass cover losses heat by convection to air at 20°C flowing over its surface at 30 km/h. Assume that the radiation heat transfer between the absorber plate and glass cover and the heat transfer through the back and sides of the collector is negligible.
