Oh ya, I put density ρ in kg / L ... At least I think :sorry:

I took another gander at the equation for the velocity of sound through gas that you linked again. I noticed an alternate definition for the bulk mod β. Can you please confirm whether the following is true? β = P(equilibrium) / ρ γ = β / P(equilibrium) I used these two definitions in a problem...

I see the π now. Thank you. I was looking for a squiggly line on the top; that's why I missed it. Thanks for the response altogether really. I saw that equation before. I just didn't remember/bother to write it down because the one definition of the adiabatic constant (idk which of your symbols...

Homework Statement Suppose a tube is filled with helium gas at a pressure of 0.11MPa and a temperature of 297K. If a piston of area of 400mm2 at one end of the tube creates sound by moving sinusoidally with a frequency of 60Hz, creating a wave with amplitude of 3.8mm, what power goes into (I'm...
