Astm Table 54b Excel [better] Today

Function VCF_54B(density15 As Double, temperature As Double) As Double ' This is a conceptual VBA function. Real implementation ' requires the 1980 ASTM calculation algorithms. ' VCF = EXP(-alpha * (T - 15) * (1 + 0.8 * alpha * (T - 15))) ' (Where alpha is derived from density15) End Function Use code with caution. 4. Step-by-Step Example Calculation in Excel Let us walk through a practical scenario: Gasoil Observed Density (15°C): 850 kg/m³ Observed Temp: 25°C Observed Volume (GOV): 1000 m³ Steps:

The constants vary by density to account for different physical properties of the products: Density Range ( is less than or equal to 770 is greater than 770 is less than 778 Transition Zone (See Transition Formula) is greater than or equal to 778 is less than 839 is greater than or equal to 839 Note: In the Transition Zone, Implementing in Excel To build an automated calculator in Excel: Input Cells : Define cells for Observed Temperature (e.g., ) and Density at 15°C (e.g., Logic for Alpha statement to select the correct based on the density in VCF Calculation : Apply the formula using the function for Astm Table 54b Excel

(Coefficient of Thermal Expansion) : Calculated using the density of the product at 15 ∘raised to the composed with power D15cap D sub 15 . 📊 Constants for Different Products Table 54B uses specific constants ( ) based on the density of the refined product: Product Type Density Range ( K0cap K sub 0 K1cap K sub 1 Transition (Special A/B) Jet Fuel / Kerosene Fuel Oil / Diesel 💻 Building it in Excel (Step-by-Step) You can set up a basic calculator without needing macros. 1. Input Cells Cell B1 : Density @ 15°C ( Cell B2 : Observed Temperature ( ∘raised to the composed with power Cell B3 : Observed Volume ( 2. Intermediate Formulas Temperature Difference ( ΔTcap delta cap T ) : =B2-15 Thermal Expansion ( ) : Use an IF statement to pick the correct based on density. 000 × 0.9832 = 983

Calculate the Standard Volume (Volume at 15°C): Standard Volume = Observed Volume × VCF Standard Volume = 1,000,000 × 0.9832 = 983,200 liters 200 liters For accurate results

For accurate results, it's crucial to ensure the API gravity values are within the specified ranges: for products with densities 653–778 kg/m³, temperatures from -18°C to 95°C; for 778–824 kg/m³, -18°C to 125°C; and for 824–1,075 kg/m³, -18°C to 150°C.
