Volume calculation formula for vertical oil storage tanks
Thread Content
Teachers: We are an oil refining company, and the oil storage tanks have not been calibrated by any relevant parties; it was the formula established by our management at that time: Volume V = h*S + 0.105*h² (Volume = liquid level height * bottom area of the tank * 0.105 * square of the liquid level)； Mass M = V * (1 + 0.000036 * (t – 20)) * VCF * (density – 0.0011) ； Moreover, the coefficients for each type of storage tank are different ； I would like to ask the experts: how is the volume of vertical storage tanks of various types and capacities calculated, and what do the constant coefficients in each formula represent? Thank you
May I ask how to calculate the volume from the liquid level of a spherical tank?
0.105 has an unclear meaning; 0.000036 is the expansion coefficient of the steel plate, and 0.0011 is the volume correction factor
0.105 may be the static pressure correction coefficient
Our tanks are calibrated at the **large-capacity first metering station, and a software is also provided. After entering the tank number, liquid level, and temperature (using the levels and temperatures displayed by the DCS), the mass and volume are calculated directly. We use software to do the quantity calculations. However, for commodity inspection and measurement, no software is used; calculations are done directly by applying formulas.
