Annotation: When the rate of oil outflow from defect cracks of damaged pipeline is calculated, it is proposed to account for sudden changes in the regime of outflow accompanied by lower rate of escaping liquid.


Key words: failure oil trunk line, oil outflow from defect holes, calculation of the outflow regimes.
