Calculating PhiG: Understanding the Phase Difference Between Waves at w=1

AI Thread Summary
PhiG represents the phase difference between two waves at w=1, calculated as phiG = (delta t/T)*360. The calculation provided, phiG = (0.5/2pi)*360, yields 28.6 degrees, but the user is not achieving the expected results. The equation wt + phi = 2pi is referenced, though its origin is unclear. The discussion highlights a diagram issue where waveforms appear distorted near t=0, suggesting this region should be disregarded for accurate analysis. Understanding the concepts of period and phase delay in sine waves is emphasized as essential for mastering the topic.

Given w =1, What is phiG ? Is it the phase difference between the two waves? If it is, isn't it simply phiG = (delta t/T)*360 but I am not getting the right answer.

PhiG = (0.5/2pi)*360 = 28.6

Also I don't know where this wt + phi = 2pi equation comes from.

The period appears to be about 6.3 s

The diagram is drawn wierdly. The waveforms appear to have a fixed phase difference everywhere except near t = 0 where one has been deliberately distorted to force it through the point (0,0). That origin region would be best ignored, it is so wrong.

There is also a +/- sign associated with the phase difference, according to whether the system introduces a lead or lag, respectively.

I think you should do a google search on: period and phase delay of sinewave
as mastery of this fundamental material is crucial.
 

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 '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...
