Storage and Flow of Bulk Solids
When I became an adjunct professor at the University of Rhode Island, I realized that most books on the subject of bulk solids testing and hopper design were either very terse or rather intense for readers who did not have a mechanical engineering background. My students encouraged me to convert my course material into a text book. Yes, some of the text may have been taken from my prior publications, but I figure that it isn’t plagiarism when you copy your own material. I only disclose analyses and design methods that are available in the open literature.
A few of the formulas I derived on my own, but they were all based on fundamental engineering principles. Consequently, some of the analyses that I present may be slightly different than what you might find published elsewhere, but I use them when I consult.
The paperback is 200 pages long and includes sections on analysis of stress, stresses in hoppers, flow property testing, bin design, feeders and flow aids, chute design, and design of process vessels.
The publisher charged me $5.00 per book, but the catch was I had to purchase one hundred of them! So I'm offering them on my website for $20.00, which includes USPS media rate snail mail shipping. For every book I sell, I either give a free book to a University of Rhode Island Student or make a donation to https://unitedhelpukraine.org 🇺🇦. I figure that if I'm charitable, I won't get into too much trouble for helping myself to some images from the web without permission.
You can pay me by credit card or PayPal. Please send an email to greg@mehos.net when you place an order if you have questions about international delivery options.
You can always download an abridged version from my downloads page. The unabridged version can also be downloaded but it requires a password. If you ask me nicely, I'll share it with you.
