  • Wenzel, Harry G. (University of Illinois at Urbana-Champaign. Water Resources Center, 1973-12)
    An experimental and analytical study was performed to develop the geometry for a Venturi type flow meter for use in sewer flow measurement. The meter consists of a constriction in the pipe which produces critical flow under ...
