Least-Cost Design of Urban-Drainage Networks
Network layouts were assumed to be known from previous planning activies; inlet hydrographs were arbitrarily chosen. The optimization problem was posed as an N-stage sequential process;...
Some Basic Concepts on Flow in Branching Conduits
Phenomenological explanations are given of the mechanisms associated with nondisturbed and disturbed flows in branching conduits, as well as straight ducts. Four categories of flow conditions...
Final Report of the Task Committee on Branching Conduits
The purposes of investigations on branches are basically to determine energy losses; pressure fluctuations including cavitation; and the relation of hydraulic losses to structural considerations...
Kamburu Dam: Diversion Conduit Designed into Spillway Saves $1,000,000
Careful coordination of dam construction operation with river stages over several seasons, and a construction sequence that called for building the spillway, in effect, from the top down,...
Turbulent Flow in Very Noncircular Conduit
Measurements of the friction factor variation with Reynolds number, and the mean streamwise velocity and boundary shear distributions, are presented for a smooth conduit having a cross...
Behavior of Underground Box Conduit in the San Fernando Earthquake
Resistance Equation for Alluvial-Channel Flow
The equation developed by Keulegan for resistance to turbulent flow in uniform rigid-boundary conduits can be used (with reasonably accurate results) to represent resistance to turbulent...
Air-Entrainment in High Head Gated Conduits
For the successful operation of high head gated conduits, adequate supply of air is of paramount importance. However, no dependable solution is yet available to determine the required...
Design of Conduit System with Diverging Branches
The capability of a dynamic programming conduit design technique was expanded to cover systems with diverging branch pipelines. An interactive computer programming approach was used in...
Modification of an Existing Pump Discharge Conduit to Accommodate Turbine Flow
Seismic Supports for Electrical Cable Systems
Seismic Category I supports for electrical conduit and cable tray systems are described. Types of supports and their analysis, design, and installation are also presented. Approximate...
Finite Element Solution for Flow in Noncircular Conduits
Typical solutions for conduits of various shapes are presented. For turbulent flow the solution is based on the validity of the use of an eddy viscosity concept to account for the Reynolds...
Discharge and Travel Time for Ground-Water Conduits
A system of mathematical and graphical procedures gives solution for the steady-flow discharge and travel time for nonuniform confined ground-water conduits in which any or all of the...
Turbulent Flows Past Boundaries with Small Streamwise Fins
An experimental investigation was conducted to determine the effect of small streamwise fins on the average boundary shear stress of turbulent flows in conduits. The experiments were performed...
Emergency Redesign of Silver Jack Spillway
A massive landslide destroyed the nearly completed spillway stilling basin at Silver Jack Dam in Colorado. Geologic conditions at the site, the extent of the slide, subsequent damage,...
General Considerations of Flow in Branching Conduits
Swimming Performance of Arctic Grayling
Solutions for Lateral Outflow in Perforated Conduits
Many applications in varied fields of engineering design require a uniform discharge in a perforated conduit. This paper gives general solutions for obtaining a uniform lateral outflow,...
Potential Flow of a Two-Dimensional Conduit Outlet
A theory is presented to describe the potential flow of liquid at a two-dimensional conduit outlet. A detailed description of the flow is given by an integro-differential equation derived...
