AI Thread Summary
To effectively capture dust in a room, a simple and cost-effective solution involves using a square or rectangular fan. By attaching a regular air filter to the intake side of the fan, it can efficiently circulate air and trap dust particles. Running the fan on low or medium speed will enhance its dust-catching capabilities. For optimal results, keeping the fan running continuously is recommended. This method provides a practical way to reduce dust accumulation, especially in winter when windows cannot be opened.

Any ideas on how to build a device that captures dust from the air?
My room is full of it because I store all my clothes here, and I can't keep the window open for long as it's winter and it's really cold...

If simple, and cheap is important, you can find a square or rectangle shaped fan at a discount store, on the intake side, tie or tape a regular air filter to the frame, and run it on low or med speed. This will circulate the inside room air, and remove most of the dust, if your not pinching pennies, let it run continually.
 

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'How can I find the cleanout for my building drain?'

I am a long distance truck driver, but I recently completed a plumbing program with Stratford Career Institute. In the chapter of my textbook Repairing DWV Systems, the author says that if there is a clog in the building drain, one can clear out the clog by using a snake augur or maybe some other type of tool into the cleanout for the building drain. The author said that the cleanout for the building drain is usually near the stack. I live in a duplex townhouse. Just out of curiosity, I...
