This photo is a picture of my lofted bed next to a large two-paned window. This is just one of two windows in my dorm room in De Smet Hall.
The concept that I will discuss regarding my photo is thermodynamics and transfer of heat. Specifically, I will be discussing conduction from the temperature outside of De smet and the temperature of my dorm room. The material that the energy will transfer through is the two large two-paned windows that are on each wall. I will complete example calculations by measuring the calculating the area of the windows and the temperature inside and outside.
During the cold Spokane morning, my roommate and I care about the temperature in our room very much and prefer not to be freezing and trying to watch Netflix. A major aspect of my photo will be discussing temperature. Temperature is defined …show more content…
The thermal conductivity constant of the material (k) is glass, which found in the physics textbook is .80 J/smC° (Cutnell, 2012). Using a meter ruler, I measured the length of my window as 1.70 m and the width as 1.10 m. When multiplying these two values to find the Area (A), the value calculated was 1.87 m2. According to the Accuweather.com, choosing a random date of December 16th, the average outside temperature in Spokane, Washington was 3.33 C° (Tc). The temperature that the rooms in De Smet are kept at during the winter according to plant services is 21.11 C° (TH). In the equation, ΔT is TH-TC because the energy will always transfer from hot to cold and both values need to be known to get a correct Q. The time that will be chosen is 45 minutes, which needs to be transferred to seconds, which is 2700 seconds. Lastly, the length of the mirror is hard to measure due to my window being on the fourth floor, so I found a double-paned window with the same area on TheHomeDepot.com and learned the thickness was .00476
