The heat will transfer faster through the water, than through the Styrofoam fin, so if I treat it as a separate element, my approach would be as follows: (See attachment for reference to Face A & B)
Q / t = Area * (T-hot - T-cold) / thermal resistance (R-factor)
For Box 1: (160 in2)...
Thanks Russ, I suspected that the equation I am using doesn't properly account for how the fin is channeling heat.
For box 2 I used 172 in2 or 1.1944 ft2 as the area. I used 160in2 (1.111 ft2) for box 1. The fin adds 16 in2, but also reduces 4 in2 where the fin touches the top and bottom of the...
I’m trying to understand the difference between how two styrofoam boxes of water cool when placed in a freezer.
see attachment for picture
Both boxes are 6’’ wide, 10’’ long and 6’’ high.
Both boxes have an internal cavity of 4x8x4 (1 inch of insulation on all 6 sides)
Box 2 has an...
