Conversion of Kinetic to Potential Energy in Flow Expansions

Information on the energy changes that occur when fluids flow in expanding conduits is presented in this paper. Specific data are presented on mean velocity distribution, turbulence, and pressure changes for 7.5°, 15°, 30°, and 180° expansions from 2.75-in. to 4.75-in. pipes. The velocity and turbulence measurements were made by photographing, on motion-picture film, the flow in transparent conduits. The water therein had suspended in it small, immiscible droplets which formed streaks on the pictures, from which the direction and magnitude of the velocity at any instant in two dimensions could be obtained.
