Inquiring into the Maximum Safety Fieight of Containing Oil in Vertical Tank

For the precise and simple determination of the maximym safety height of containing oil in vertical tank, the author makes a detailed analysis on such four factors that would influence the calculating precision. In the same time, he also points o it that there are same deficiency in the calculation of refe-rence1 and 2, thus he puts forward a calcolating formula for the maximUm safety height of containing oil and safety vol'me in vertical tank. Based on practi-sas and examples, it has been proved that this calculating method has such advantages as high precision and simple and practical application, and is su-itable to be used for various oil products, all kinds of tank and different con-dition of storage so that the safety of oil tank is ensured.
