Calculation of air-permeable rigid pipelines
Authors:
Abstract
Calculation of mine air ducts by analytical and graphoanalytical methods is mainly reduced to the determination of two values: 1) air leakage or delivery coefficient μ; 2) head h, which is necessary to create, so that to the end of the stack of pipes a given amount of air Qzab. Many formulas for calculation of these values have been proposed. A. I. Shvyrkov on the basis of theoretical studies of air movement in air-permeable pipelines established a functional dependence between the values of.
