Abstract
An investigation was conducted to make pressure drop design data available for commercially marketed converging flow fittings used in industrial ventilation exhaust systems. The investigation included an experimental study and an analytical study. Forty nine fittings over a wide range of sizes were studied in the experimental phase. The recommended geometry of a converging flow fitting consists of a tapered mainstream with a branch entry angle of thirty and forty five degrees. The analytical study consisted of developing semiempirical equations which would be applicable to fittings with tapered mainstreams and thirty, forty five, or ninety degree branch angles for all combinations of branch, upstream, and downstream diameters.
