Uniform Distribution of Flow in Combined Pipe Line Nets

Abstract

The pipe line nets which have two parallel main pipes combined with many branch pipes, are widely utilized in the industrial field, and it is often required to distribute the flow uniformly through each branch pipe. In this paper, a method of flow control is investigated for this pipe line system, and we have derived a calculating formula of controled resistance value to make the flow equation satisfy in parallel or counter flow type pipe line. And we used the orifice as the controlling resistant body to be inserted in the branch pipe and observed its effect in comparison with the experiment and the theoretical calculation.
