Astm Table 54 Excel |link| -

alpha = K2 / (Density15 ^ 2) dt = TempObs - 15

=B3-15 Step 4: Calculate VCF using series expansion (Excel does not have a direct liquid expansion function). Use the exact API formula: astm table 54 excel

Step 2: In cell B5, calculate thermal expansion coefficient: alpha = K2 / (Density15 ^ 2) dt

This 2-term approximation is valid for most industrial ranges (±0.0002). For higher precision, use: But Excel-friendly: In cell B6: [ VCF =

(Where D15 = density at 15°C, T15 = observed temp) | A | B | C | |---|---|---| | 1 | Density @15°C (kg/m³) | 850.0 | | 2 | Observed Temp (°C) | 35.0 | | 3 | Product Type | Product | | 4 | Alpha | =IF(C3="Crude",341.0957/B1^2,594.5418/B1^2) | | 5 | dt | =B2-15 | | 6 | VCF | =EXP(-B4 B5 (1+0.5 B4 B5+(1/6) B4^2 B5^2)) | | 7 | Volume at 15°C | = (Enter gross volume) * B6 | This paper provides a complete, ready-to-implement guide for creating, validating, and using ASTM Table 54 in Excel for professional hydrocarbon measurement.

But Excel-friendly: In cell B6:

[ VCF = \exp\left( -\alpha_15 \Delta t \right) \cdot \left(1 - 0.5 \alpha_15^2 \Delta t^2 \right) ]
