this is more of a numerical analysis question..so I am not sure where to post it..(also put it up in the computers forum)


im wondering, I've seen examples of ill conditioned matrices with small determinants...but what would be an example of a well conditioned matrix with a very small determinant?

I've deleted your other posts and issued you a 1-point warning for posting multiple copies of the same question. Do no multiple-post. That is not allowed here on the Physics Forums (PF), or on any other forum system that I'm aware of. I'll leave this one thread here, since it seems like the best match so far for your question.
 
oh sorry! i must have overlooked that in the rules :(

but..the good news is i finally figured one out! so forget this question
 
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...
I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
