Astm — Table 54 Excel [patched]
Use in Excel: =ASTM_Table54_VCF(B2, B3, B4) 6.1 Comparison with Official ASTM Table 54 (Excerpt) | Density15 (kg/m³) | Temp (°C) | Official VCF | Excel VCF (2004) | Delta | |------------------|-----------|--------------|------------------|-------| | 800.0 | 20.0 | 0.99565 | 0.99566 | +0.00001 | | 850.0 | 30.0 | 0.98234 | 0.98233 | -0.00001 | | 900.0 | 45.0 | 0.96891 | 0.96890 | -0.00001 |
Step 2: In cell B5, calculate thermal expansion coefficient:
=IF(B4="Crude", 341.0957/(B2^2), IF(B4="Product", 594.5418/(B2^2), NA())) Step 3: Calculate Δt (temperature difference): astm table 54 excel
[ \alpha_15 = \fracK_1\rho_15^2 + \fracK_2\rho_15 + K_3 ]
[ VCF = \exp\left( -\alpha_15 \Delta t \left(1 + 0.5 \alpha_15 \Delta t\right) \right) ] Use in Excel: =ASTM_Table54_VCF(B2, B3, B4) 6
=B3-15 Step 4: Calculate VCF using series expansion (Excel does not have a direct liquid expansion function). Use the exact API formula:
(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.
