A steam pipe is covered with 1.50-cm thick insulating material of thermal conductivity of 0.200 cal/cm · °C · s. How much energy is lost every second when the steam is at 250°C and the surrounding air is at 20.0°C? The pipe has a circumference of 800 cm and a length of 64.0 m. Neglect losses through the ends of the pipe. ?MW
An electric stove burner has surface area 325 cm² and emissivity e = 1. The
burner consumes 1500 W and is at 900 K. If room temperature is 300 K, what
fraction of the burner's heat loss is from radiation?
Electronics and inhabitants of the International
Space Station generate a significant amount of
thermal energy that the station must get rid of. The
only way that the station can exhaust thermal
energy is by radiation, which it does using thin,
1.7 m -by-3.8 m panels that have a working
temperature of about 6° C.
How much power is radiated from each panel? Assume that the panels are in the shade so that the absorbed
radiation will be negligible. Assume that the emissivity of the panels is 1.0.
Express your answer with the appropriate units.

The temperature of the furnace room, including its surfaces, is 30°C, and the emissivity of the outer surface of the furnace is 0.7. It is proposed that this section of the furnace wall be insulated with glass wool insulation (k = 0.038 W/m·K) wrapped by a reflective sheet (« = 0.2) in order to reduce the heat loss by 90 percent. Assuming the outer surface temperature of the metal section still remains at about 110°C, determine the thickness of the insulation that needs to be used. The furnace operates continuously throughout the year and has an efficiency of 78 percent. The price of the natural gas is $1.10/therm (1 therm = 105,500 kJ of energy content).
