Hydraulic Performance of Penstock Trifurcations
The pressure distributions and the energy losses were obtained in an air tunnel for the following penstock trifurcations: a two-wye arrangement, two types of plug-funnel proposal, and...
Reinforcing Steel for Penstock Wye Branches
To avoid using heavy ring girders with welding problems, a reinforcing steel solution was developed for the Blakely Mountain penstock wye and surge tank riser. This solution was practical...
Aqueduct Route Optimization by Dynamic Programming
The structure of a regional irrigation project supplying water to a number of villages scattered over a relatively flat area is modeled by a series of straight lines across the contours,...
Boundary-Layer Development at Curved Conduit Entrances
To gain a better understanding of the energy reduction in a conduit inlet shaped according to potential-flow theory, boundary-layer measurements were made in a nonrecirculating air duct...
Distribution of Energy Losses at Conduit Trifurcations
An equation for the estimation of energy losses occurring in individual branches of a trifurcation is presented. Experiments were conducted for division of flow on nine trifurcations with...

Plastic Design of Flexible Conduits
Minimum Cover For Buried Flexible Conduits
From model studies it is possible to predict the minimum soil cover required to protect buried conduits over which a wheel load passes. Similitude is achieved by drawing fluid (air) down...

Discussion of "Dispersion Conduits" (February 1968)
Reducing Cavitation in Valves
Critical cavitation indices are presented for a 12-in. ball and a 12-in. butterfly valve installed in a closed conduit with an enlarged section downstream. Tests were conducted under normal...
Dispersion Conduits
A dispersion conduit is a pipe or flume designed to distribute a fluid almost uniformly throughout its length through outlets consisting of a series of orifices, gates or branch pipes...
Review of Cavitaion Research on Valves
Critical cavitation indices are presented for a 12-in. ball and a 12-in. butterfly valve installed in a closed conduit system with, a sudden expansion downstream of the valves. Tests were...
Measuring Solid-Liquid Mixture in Closed Conduits
Much attention has come to the transportation of solids in a liquid in closed conduit. Measuring devices to measure the pertinent parameters of solid-liquid flow have been tried and used....
Plastic Design of Flexible Conduits
A design procedure for circular underground flexible conduits is presented. The method is based on the formation of a collapse mechanism in contrast to the deflection criterion which is...
Dworshak Dam Spillway and Outlet Hydraulic Design
Hydraulic design of spillway and outlets for 693-ft-high concrete-gravity dam utilizes model studies in developing final design. Tainter valves provide upstream control in the three outlet...
Some Analytical Results for Planet 90° Bend Flow
Analysis of inviscid nonturbulent flow around bends preceded and followed by straight conduits on a potential and frozen-vorticity basis indicates the manner in which bend curvature and...
