AI Thread Summary
Sampling frequency is a crucial factor in rendering physical reality, but it is not the only one. Temporal resolution must be at least twice the dominant frequency of the system for accurate modeling. Spatial resolution and range are equally important; using inappropriate transducers can lead to significant measurement errors. The discussion highlights the need for a comprehensive approach that considers multiple factors in rendering physical reality. Accurate modeling requires balancing sampling frequency with other critical parameters.

Hello all,

as far as rendering physical reality, isn't sampling frequency the main thing ?...

I don't understand your question, rendering physical reality and sampling are two different things. Samples can be used to validate models that render physical reality. The temporal resolution is important depending on the dominant frequency of the system. Your sampling frequency should be twice that. I don't know why this should be the main thing. spatial resolution and range are just as important. I you try to measure pressure oscillations of 0-1000 psi with a 0-10 psi transducer your in trouble regardless of the transducer's time constant.
 

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...

Thread 'Dry sump pump issue'

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...
