thank you very much for your answer,
do you know of any book/article where the theoretical limit of movement for creating an acoustic wave is calculated/shown (considering the pressure/temperature as you have mentioned)?
thank you again for your help
I have a question regarding the implication of mean free path and pressure acoustics.
I have seen several publications on the internet and also calculated the minimum displacement of a wave in air using the formula
dp=v * rho * *2*pi*freq. * dx
The values of displacement can...
Thank you for your question and sorry for the late reply
(I had to read a bit and get confused again before answering :-))
These should be the assumptions for the Bernoulli equation:
Inviscid flow (ok in this example)
Constant density (respected in this example)
Along a streamline...
I have a simple question regarding how to calculate the speed of a fluid in a normal pipe with a constant cross-section
If we are given the pressure difference at the two ends of the pipe (P1 and P2) is it possible to calculate the speed of the fluid? (I think I can imagine this...
I have a question regarding radians and the unit of rotational energy (which has been probably asked several times elsewhere but is still confusing for me :-) ).
As I understand radian (rad) is a UNIT that is dimensionless (thus cannot be omitted), correct ?
Now if I want to...
I am stuck with a problem about voltages (electrostatic potential) and forces.
According to capacitor equations the energy stored in the capacitor is:
And force is:
F = - dU/dx
Since U is dependent on V^2, our force can’t be positive (repelling...
