Hello All. Quick into, I am an absolute newbie and haven't even attempted my first refine yet. Long story short I had a very serious health issue (abated hopefully) and it made me realize I need to empty the bucket a little so to speak. I've always wanted to do precious metal refining and micro scrapping and have spent the last 9 months studying up and planning. I renovated my 12' x16' shop to be a bit more comfortable place to recover and refine. I've been reading Hoke but admittedly am only half way though it (extremely informative but not exactly a page turner if you know what I mean). I've also been visiting the forum and researching, reading, and watching lots of youtube videos on various topics related to the process.
I have completed my shop table with melamine top and am in the process of building the hood (also melamine). Before I went any further and started using flex seal on the crevices or drilling holes in the wall I wanted to run my design plan by you folks and see if you think my fan will be capable of handling the size of the hood. The hood just seems a lot bigger than I imagined.
The face of the hood is 39 3/4 inches by 34 1/2 inches. So my calculations are thus
Facex100/144=CFM
39.75 x 34.25 x 100 / 144 = 945.44 CFM
The fan I have is a12 inch fan rated at 1060 CFM.
I think it should work but since I am using a Venturi design I am not how much it reduces the equations.
Any thoughts, comments, suggestions, and advice would be appreciated.
P.S. I hope the .pdf file of my concept plan downloads but if not I can explain the design as well. The pieces with fan on the table are for the reduction of 2 inch and 4 inch pvc pipe.
