Calculating Speed of sound in NH3 2

[ErikHeld]

Hi,

I have been looking for an equation to calculate the spee do sound on liquid ammonia. Does anybody know where I can find this information?

 

[SNORGY]

For liquids:

c = [K/r]^0.5 where K = bulk modulus and r = density?

Try also this thread on this site:

Thanks, I did find that equation but I now have no idea on how to calculate the bulk modulus of ammonia. Do you know of any resources that you can point me to to calculate this based on my actual temp and pressure?

go to fluid properties and you"ll get the speeds of sound under the conditions you select.

I'm late to arrive here, but 25362's response is absolutely representative of a GREAT helpful answer. Somebody shoulda' pasted a star at the time, but I will now.
