Combining Flow in Branches and Wyes
Cavitation in High-Head Conduit Control Dissipators
The wasting of water from high-head hydraulic structures through a closed conduit requires an economical control and energy dissipator device which will safely contain the potentially...
Closure to "Design Conduit System by Dynamic Programming" (March 1971)
Effect of Axial Flow on Perforated Pipe Outflow
There has been considerable past study, mostly of a theoretical nature concerning the flow of fluids in conduits with perforated or porous walls. This technical note deals primarily with...
Effects of Mechanical Cleaning Operations on Flow in Large Conduits
By following a systematic cleaning and maintenance program in recent years, the Colorado River Aqueduct has been kept in condition to deliver substantially greater flows of water to the...
Penstocks for Six Pumped Storage Projects
High head pumped storage plant designs have required drastic changes in steel plate specifications and welding procedures for penstocks and tunnel liners. Salient data are reviewed for...
Sizing of Pumped Storage Conduits
Determining the economic diameter of hydraulic conduits, tunnels, pipelines, or penstocks, requires minimizing the total cost (capital plus OM&R) of those elements which are a...
Discussion of "Design Conduit System by Dynamic Programming" (March 1971)
Closure to "Flow in Conduits with Low Roughness Concentration" (April 1970)
Cement Stabilized Fill for Conduit Support
A compacted sand and gravel fill, stabilized with cement, was used to provide an economical foundation under a portion of the outlet works conduit at Cochiti Dam in north central New Mexico....
Design and Construction of Mossyrock Penstocks
Foundation conditions required that the powerhouse be located close to the arch dam, resulting in relatively short, straight runs of penstock. Preliminary computations indicated that...
Design Conduit System by Dynamic Programming
A method, based on dynamic programming and systems concept, was developed for optimizing fluid distribution system. It allows design to proceed by stages to avoid the difficulty of making...
Steel Penstock Design for Tims Ford Dam
The design and construction of an embedded steel penstock is discussed. A straight line trench, from intake to powerhouse, cut into the rock under the left side of the dam reduced construction...
New Design Criteria for USBR Penstocks
New design criteria for nonembedded and embedded penstocks as adopted by the Bureau of Reclamation are presented. Nonembedded penstocks include supported penstocks exposed to view and...

Flow in Conduits with Low Roughness Concentration
Transition functions which relate the friction factor and the relative roughness to the Reynolds number are obtained by utilizing the basic laws for turbulent flow in conduits plus the...
Closed Conduit to Open Channel Stilling Basin
Criteria have been developed for designing a stilling basin to serve as a transition from closed conduit flow to open channel flow for a fully submerged pipe outlet. The unique feature...
