We are studying the waterhammer in a Refinery. Since the bulk modulus is involved in this study, we will like to know where to find the bulk modulus at different temperatures and pressures for several refinery fluids such as kerosene, diesel, atmospheric and vacuum residue.

We have found some info about kerosene in the handbook of aviation fuel properties, but not further information has been found in the net.

Thanks for your cooperation

I had a search on google long back and had found one google-book hit which gave following relation for isothermal bulk modulus as function of temperature, pressure and API gravity of fluid.

Bulk modulus = A+B*P-C*(T^0.5)+D*(T^1.5)-E*(API^1.5)

where

A = 2.62E6
B = 9.203
C = 1.42E5
D = 73.05
E = 3.41E2
P = Pressure in psig
T = Temperature in deg Rankine
API = API gravity of fluid

I don't remember the name of the book, but it is certainly available in google books. Please confirm before using with a known fluid.

Hope it helps.
