Question 1: A glass window of width W = 1 m and height H = 2 m is 5 mm thick and has a thermal conductivity of kg =1.4 W/m.K. If the inner and outer surface temperatures of the glass are 15 oC and -20 oC, respectively, on a cold winter day, what is the rate of heat loss through the glass? To reduce heat loss through windows, it is customary to use a double pane construction in which adjoining panes are separated by an air space. If the spacing is 10 mm and the glass surfaces in contact with the air have temperatures of 20 oC and -15 oC, what is the rate of heat loss from a 1 m x 2 m window? The thermal conductivity of air is ka = 0.024 W/m.K.
A wall in a house contains a single window. The window consists of a single pane of glass whose area is 0.13 m2 and whose thickness is 8 mm. Treat the wall as a slab of the insulating material Styrofoam whose area and thickness are 19 m2 and 0.10 m, respectively. Heat is lost via conduction through the wall and the window. The temperature difference between the inside and outside is the same for the wall and the window. Of the total heat lost by the wall and the window, what is the percentage lost by the window?

Sputnik 1, the first satellite launched into space by the Russians in 1957, is a 2-shell aluminum alloy (2024-T6) sphere. The highly polished outer shell (seeing deep space) is 585 mm in diameter, and has thickness of 1 mm (ID = 583 mm). The inside shell is 2 mm thick. There is a contact resistance between the two aluminum shells of value Rc"= 200 m2·K/W. Inside the shell, there is a radio unit that is uniformly dissipating thermal energy of Qradio = 1 W. Determine the steady-state temperature on the inner shell’s inner wall (ignore the effects of the antennas). Hint: You can use a radiation heat transfer coefficient hr = εσTshell3

You want to figure out whether it is safe to touch the outside surface of the pipe in question. Here are the details: "A stainless steel pipe is carrying hot water to a test facility. The inside surface of the pipe is at a temperature of 70°C and the inner radius is 0.2 m. The thickness of the steel pipe is 12 mm. It is exposed to air at 30°C on the outside. The average convection coefficient of air over the pipe is 15 W/m².°C. Thermal conductivity of steel is 54 W/m.°C. Negelect radiation. Consider steady conditions." Calculate, assuming a 1-m long pipe segmen, the temperature of the outside surface of the pipe.
