Product Data
The above tables are derived from equations, which form the basis of the data in the Revised
Petroleum Measurement Tables (IP 200, ASTM D1250, API 2540 and ISO R91 Addendum 1).
The density temperature relationship used is:
Where: = Density at line temperature t°C (kg/m
3
)
= Density at base temperature 15°C (kg/m
3
)
= t°C –15°C (such as t – base temperature)
= Tangent thermal expansion coefficient per °C at base temperature 15°C
The tangent thermal expansion coefficient differs for each of the major groups of hydrocarbons. It is
obtained using the following relationship:
Where: K
0
and K
1
= API factors and are defined as follows:
