Influence degree completion horizontal cylindrical tanks while they emptied by accident

In the petrochemical industry for the storage and transportation of petroleum products are widely used horizontal cylindrical tanks. The scale of accidents resulting from the violation of their integrity, depend primarily on the rate of discharge of oil. Speed ​​depends, in part, on the degree of filling of the reservoir, which determines the initial height of the liquid column. However, the regulatory impact assessment methodologies do not take into account the failures of the receptacle, that is assumed that the initial height of the liquid column is equal to the diameter of the tank. This leads to incorrect results, unnecessarily overstate or understate the effects of the disaster. In this paper, we propose a simple method of accounting for the value of degree completion
