Bulk modulus of LPG

Bulk modulus of LPG

Bulk modulus of LPG

(OP)
Hello,

I am looking for the bulk modulus of butane and propane to perform a water hammer analysis. Any idea? After searching in Internet, Perry's, etc I have found nothing...

Thank you.

RE: Bulk modulus of LPG

You can calculate it from the accoustic velocities
which are,

Propane            2000-2500 fps
Isobutane    2200-2800 fps
N-butane    3100-3700 fps

at 68ºF and 200 psiA

RE: Bulk modulus of LPG


I was going to give you the same advice that BigInch gave you. The NIST webbook gives you sound velocities c [m/s], and the liquid densities ρ [kg/m3], at the conditions you wish.

Using metric units, the bulk modulus Y [kg/m2] is estimated from:

Y = c2 × ρ ÷ 9.8 m/s2

Thank you. Very useful information.
