    Ethanol Gas
AI Thread Summary
Ethanol gas containing 5% ethanol is now available in the town, with discussions focusing on its impact on vehicle performance and durability. Most participants agree that this low concentration has minimal effect on car power and is comparable to regular gasoline. Concerns about potential damage to engine parts are noted, but modern engines are typically designed to handle up to 10% ethanol without issues. Additionally, high concentrations of ethanol can affect certain plastics and require adjustments to the ignition system. Overall, 5% ethanol is considered safe for use in most vehicles.

Dear all,

They starts to sell ethanol gas in my town. It is only 5% ethanol as said. Concerning the power of the car, I think it's about the same. But I am not sure about the durability of some item, may it reduce the lifetime of some parts?.

Thanks for all of your contribution.

High concentrations of ethanol can have an effect on some plastics and the ignition system needs to be adjusted for the different behaviour.
But 5% ethanol has almost no effect, it's probably within the range of composition of regular gasoline!
 
Indeed, you can look on the pumps for regular gasoline. I've seen them as high as 10% ethanol IIRC.
 
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...
