A while ago I made a small structure that I called a “chiller” .. just something to stick next to a building to add interest. I figured out that when I tried to describe it to myself as “a water cooler” .. then finally a “cooling tower” that I was trying to do just that .. design a cooling tower.
Searching Google Books I found this – Cooling Towers – Wheeler Condenser & Engineering Company, Carteret, N.J. published 1922. At the front of the book it states:
That was followed by a diagram showing “The Physics of Cooling Water by Exposure to Atmospheric Air” .. and enough math to calculate the size of the cooling tower needed cool hot water from one temperature to another. This is fine for a background on the things but not that important (IMO) for modeling.
The book contains quite a variety of cooling towers with photos and drawings of each along with how many G.P.M. capacity of each structure. Now this is where the book helps modeling .. pictures .. which are always good .. something we can follow. Page 39 has a drawing of a cooling tower that caught my eye .. being that it was relatively small .. always a big plus for modeling. The text states:
One of the things that caught my eye were the ladders. With those to provide scaling I could use this drawing in Sketchup’s Match Photo to bring the little cooling tower back to life! I had promised Ron Pare once to write up something on using Match Photo .. so here goes. (click the images for a full-screen version which will open in a separate window)
|– Crop your photo/drawing as/if needed|
|The first thing I did was crop that drawing so I only had the cooling tower to work with. This isn’t absolutely necessary but it does help focus on what is the central item. I renamed graphic -Fig43.jpg to Fig43_cropped.jpg (not that original I admit .. but works for me).|
|– Download a Copy of Sketchup|
“Safe Harbor Statement” – I am using Sketchup 8 to do this. This is simply because I have the plug-ins I use where I like them and haven’t bothered switching to a newer version. This doesn’t matter as the process will be similar if not exactly the same. You can get a copy of Sketchup Make easily enough by Clicking this link. Sketchup Make is the free version – which is what I use to make 3D models – I don’t have the need to pay for the Pro version.
I’m not going to try and teach you to use Sketchup. It is IMO about as easy as falling off a log. Simply goto YouTube and enter Sketchup Tutorials in the search box. I WOULD though tell you to pay attention to “groups”, “components” and “layers” .. you can ignore that advice but you WILL regret it.
