AI Thread Summary
To design a soda/water bottle with minimal surface area, research shapes that maximize volume relative to surface area, such as spheres or cylinders. Resources on geometric calculations will help determine the most efficient designs. Nature often showcases these optimal shapes, providing real-world examples. Exploring mathematical principles and existing models can guide the design process effectively. Understanding these concepts will lead to a successful bottle design.

I have a soda/water bottle design coming up. And it requires me to find the proper shape that will have the minimum surface area. Do you know where I can find the related information on this? Where can I find some comparable models and so on? Any infor. will be helpful. Thanks.

Sounds a little bit homeworky, so I'll give you a hint.

The shape which has the maximum volume / surface area occurs frequently in nature.
 
You can easily calc out volume/surf. area for different shapes. You will converge on the most efficient very quickly.

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...

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...
