Astm Table 54 [best] Today

def vcf_table54_groupB(temp_c, density_obs_kgm3): """ Simplified volume correction factor (VCF) to 15°C. Based on typical expansion coefficients for middle distillates. """ # Approx cubic expansion coefficient per °C for Group B # Real ASTM uses complex polynomials per density/temp grid alpha = 0.00085 # 1/°C

ASTM Table 54 is part of – the Standard Guide for Use of the Petroleum Measurement Tables . It is used to correct the volume of crude oil, refined products, or lubricating oils to a base temperature (usually 60°F or 15°C) based on: astm table 54

observed_density = 850.0 # kg/m³ at 30°C observed_temp = 30.0 # °C astm table 54
