A similar graph from a another discipline is the following Basically you will need to plot for each test (which I assume had a different d/S), the values of your experiment. So for each d/S you calculated different values of the convective heat coefficient at different air speeds. So you need to plot 10 different graphs.

Most thermometric cooling modules (Peltier devices) are made out of Bismuth Telluride which has a thermal conductivity of 1.20 W/(m·K), similar to ordinary glass. From this wiki list of thermal conductivities: Copper, 401 W/(m·K) Aluminum, 237 W/(m·K) So for a given temperature differential, a thermometric cooling module in the off state would conduct 334 ...

An evaporative cooler works by removing the suspended layer of saturated vapor from around the filter, encouraging it to use the ambient heat from the stream of the air thus making it colder, to evaporate to replace the washed-out moisture. The latent heat for water is 2460 J/4.18 J per gram = 588.5 times more than specific heat. (Thanks To Phil Sweet for ...

You confused me too, lol. Lets back up. Water will only condense when moist air is cooled below its dew point. The amount of water the air can store is not important to us in this case; just when it is at the dew point. This means that in order for this system to produce any water, the night temperature must be less than the noon dew point. The final temp ...
