Bulk Modulus (for most any hydrocarbon liquid) PSI =100000*exp(1.9947-0.00013427*TempF -0.79392/SG^2-0.002326*TempF/SG^2)
TempF = Temperature of the hydrocarbon liquid Fº
SG = specific gravity at your TempF
Note: not the isothermal bulk modulus or the adiabatic bulk modulus. Adiabatic Bulk modulus is about 15% higher,
Isothermal Bulk modulus is about 15% lower.
Tabulated typical isothermal bulk modulus values for liquid petroleum fractions, from gasoline to lube oils, kerosine included, are around 180,000-190,000 psi at 15oC.
