In an electrically heated home, the temperature of the ground in contact with a concrete basement wall is 12.3 oC. The temperature at the inside surface of the wall is 20.1 oC. The wall is 0.16 m thick and has an area of 6.1 m2. Assume that one kilowatt hour of electrical energy costs $0.10. How many hours are required for one dollar's worth of energy to be conducted through the wall?

Chapter 13, Problem 01 The amount of heat per second conducted from the blood capillaries beneath the skin to the surface is 280 J/s. The energy is transferred a distance of 2.1 × 10-3 m through a body whose surface area is 1.8 m2. Assuming that the thermal conductivity is that of body fat, determine the temperature difference between the capillaries and the surface of the skin. Chapter 13, Problem 02 In an electrically heated home, the temperature of the...

ASSIGNMENT 1 Example below was discussed in class The roof of an electrically heated home is 6 m long, 8 m wide, and 0.25m thick, and is made of a flat layer of concrete whose thermal conductivity is k = 0,8 W/m.K. The temperature of the inner and the outer surfaces of the roof one night are measured to be 15°C and 4°C, respectively for a period of 10 hours. Determine (a) The rate of heat loss through the roof...

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....
