That is interesting, and I will look into that experiment. I'm working in the ultrasonic range around 40 kHz with a a bandwidth of about 2 kHz. At these frequencies, I have just assumed that 1/f noise was negligible. However, I hadn't given much thought to the shot noise. Thank you for your...

I'd like approximate the noise floor of an ultrasonic air transducer starting from molecular vibrations. Simply put, if I treat atmospheric air as an ideal gas and I confine each air molecule to exist in a volumetric cube with a square face ##A_\mathrm{face}##, then I approximate the number of...

Thank you for your kind replies! I'm understanding that my initial constraint of the air so that it can be treated as an incompressible fluid is a large misstep. After reading boneh3ad's reply (apologies, I can't seem to work out how to link your profile yet), I've also investigated the boundary...

Hi all! This is my first post here, so hopefully I am not in violation of any rules or etiquette. I'm looking to derive an equation for Reynolds number as function of pressure for a pinhole leak in a pressurized gas line. The line is regular air and is pressurized to 1 atmosphere and is leaking...
