NH3 Bulk Modulus????

[ErikHeld]

Does anybody know where I can find the bulk modulus for liquid ammonia. Thank you.

Erik,

Based on a celerity or speed of sound of 1729m/s in ammonia at -33 deg C and a liquid density of 680kg/m3 I back calculated the approximate bulk modulus K as 2.03 GPa.(approx 294,000PSI)

C = Sqrt(K/density) for a rigid pipe

I hope this helps

Mech85,

Thanks, the speep fo sound in ammonia is what i was looking for. Where did you find that value? Im new to the field and suck at looking things up.
