Hydraulic Research in the United States 1956 United States Department of Commerce National Bureau of Standards Miscellaneous Publication 218 NBS PUBLICATIONS Capacities of Plumbing Stacks in Buildings A study of the maximum load that can be brought from a horizontal branch into a stack down which water is being discharged from fixtures on higher floors. This phase of a projected complete investigation, intended to make drainage design more economical, is concentrated on the drainage stack and the building drain. The report describes tests to determine terminal velocities and terminal lengths in stacks as well as tests on stacks and drains. It analyzes stack conditions in a multistory building and suggests applications of the study's results. Order NBS Building Materials and Structures Report 132, Capacities of Plumbing Stacks in Buildings, 28 pages. Price: 25 cents. Self-Siphonage of Fixture Traps An explanation of the extent to which trap-seal losses are influenced by such considerations as the diameter of the trap and the depth of trap seal, the diameter and slope of the fixture drain, the type of vent fitting used, and the rate of discharge of the fixture. The report shows the importance of standard- izing fixture traps and the hydraulic characteristics of plumbing fixtures, such as lavatories, sinks, and trays; and it makes recommendations for use by code-writing authorities.

Wet Venting of Plumbing Fixtures An account of extensive research and laboratory tests to determine the feasi- bility of using vented one- and two-story plumbing drainage systems. The conclusions reached regarding satisfactory operation limits for wet-vented fixtures are given in a form suitable for inclusion in plumbing codes. The report describes test procedures and explains results. Diagrams, tables, and graphs are included showing the trap-seal losses that occur under various conditions of wet venting and indicating the maximum permissible unvented lengths of fixture drain.

Stack Venting of Plumbing Fixtures A report describing tests involving use of pipes, traps, connections, and vents made of transparent plastics which make all flow phenomena visible. Similar tests were made with regular metal fittings to obtain comparative data and to permit correlation of results. The report discusses and interprets results, (Continued on page 3 of cover) UNITED STATES DEPARTMENT OF COMMERCE • Sinclair Weeks, Secretary NATIONAL BUREAU OF STANDARDS • A. V.

Middleton National Bureau of Standards Miscellaneous Publication 218 Issued June 7, 1956 For sale by the Superintendent of Documents, U. S. Government Printing Office, Washington 25, D. C. Price $1.50 FOREWORD The information contained in this publication was compiled from reports by the various hydraulic and hydrologic laboratories in the United States and Canada. The cooperation of these agencies is greatly appreciated. Projects are numbered chronologically, and the number once assigned is repeated for identi- fication purposes until a project is completed. Numbers commencing with 2255 refer to projects which are reported for the first time. All projects are in active state, unless otherwise noted under (f). It is emphasized that the National Bureau of Standards does not have in its files reports or detailed information regarding the research projects reported by other organizations. Such information may be obtained from the correspondent listed under (c) or immediately following the title of the organization reporting the work. It is of course understood that any laboratory submitting reports on its work will- be willing to supply information to properly qualified in- quirers. A similar bulletin, "Hydraulic Research", compiled and published by the International Association for Hydraulic Research, contains information on hydraulic research being conducted in foreign countries. This bulletin is edited by Prof. J. Th. Thijsse, Director of the Hydraulic Laboratory at the Technical University of Delft, Netherlands, and Secretary of the International Association for Hydraulic Research. Copies may be obtained from the Secretary at $6.00 each (postage included). A bulletin entitled "Directory of Hydromechanics Research Projects in the United States Related to Naval Architecture and Marine Engineering" is prepared by the Hydrodynamics Committee of the Society of Naval Architects and Marine Engineers.
