Type of article: Article

Summary

THE PAPER ANALYZES A BASIC T-TYPE DIVIDING FLOW BY CONSIDERING THE DIVIDING ENERGY LOSSES AT BRANCHES. THE RESULTS OBTAINED ARE: 1) FLOW DISTRIBUTIONS ARE, STRICTLY SPEAKING, THE FUNCTION OF RE WHICH IS THE REPRESENTATIVE REYNOLDS NUMBER OF A PIPING SYSTEM, THOUGH THE RATE OF CHANGE IS NOT LARGE ; 2) THE ERRORS IN THE FLOW DISTRIBUTIONS AND OVERALL LOSS COEFFICIENTS CAUSED BY NEGLECTING THE DIVIDING LOSSES ARE CALCULATED AND THEIR CHARACTERISTICS ARE ILLUSTRATED IN SEVERAL GRAPHS ; 3) THE IDEA, < AMONG THE FLOW DISTRIBUTIONS IN A PIPING NETWORK WHICH SATISFY THE THEOREM OF CONSERVATION OF MASS, THE TRUE AND COMPATIBLE FLOW DISTRIBUTION HAS THE LEAST HYDRAULIC ENERGY LOSS IN THE NETWORK > IS NOT VERIFIED IN THE CASE OF T-TYPE DIVIDING FLOW.
