The Value of Model Testing in Computer Aided Pump and Turbine Design
This paper discusses the importance of model testing for development and sharpening of interpretive techniques through which computational codes can be effectively used for the design...

Design Data of Pump-Turbine and Francis Turbine Units
Some basic statistical data covering geometrical and energy parameters for Francis turbine and Pump-turbine units are presented. These data are further compared as specific ratios for...

Potential for Upgrading the Robert Moses Niagara Power Plant
This paper summarizes the feasibility of increasing the generating capacity of the Robert Moses Niagara Power Plant by replacing the turbine runners, upgrading the generators, and replacing...

Development of Three Systems Operated Rev. Pump Turbine
In order to represent the development of reversible, single stage pump turbines in Yugoslavia, the three systems operated pump turbine (3SRPT) of the fourth unit of Moste hydro power plant,...

Sewage Plant Engineered for Value
The Camden County (NJ) Municipal Utilities Authority was formed in 1972 to cope with suburban growth that had overloaded 34 primary treatment plants. By the early 1990s, the Authority...

Probabilistic Structural Response of a Turbopump Blade to Random Pulse Loading
The objective of this work is to develop probabilistic models of the response of a Space Shuttle Main Engine (SSME) turbopump blade to random impact loading. These loads are caused by...

Sanitary Sewer System Modeling for Operation and Planning
Development of a Steady State Sanitary Sewer Simulation (S5) computer model helped Newport News, Virginia, enact an efficient sanitary sewer management...

Conjunctive Use Study of Groundwater and Surface Water in Chino Basin, California
The purpose of this paper is to study the effects of artificial recharge on an already contaminated unconfined aquifer and propose optimal recharging and pumping schemes to prevent the...

Methodology for the Optimal Reliability Based Design and Analysis of Pumping Systems for Water Distribution Networks
A methodology has been developed for the optimal (minimum cost) reliability based design of pumping systems. Two computer simulators, a reliability simulator and a hydraulic simulator,...

Optimal Pump Operation Using Nonlinear Programming
This paper focuses on the operational control problem of determining the optimal pump operation policy for a given distribution system. The optimal pump policy is defined as that schedule...

Regional Assessment of Pumpage in Southeastern Virginia
A U.S. Geological Survey investigation was conducted, in cooperation with the Virginia Water Control Board, to analyze the hydrogeology and groundwater flow system in the Coastal Plain...

Hydrogeology of a Barrier Island System, Nags Head, North Carolina
The purpose of this research was to understand the dynamics of the water table prior to the start of municipal pumping and to predict the effect that the pumping would have upon the water...

A Ground Water Modeling Effort to Simulate the Results of An Aquifer Restoration Scheme
A ground water model using the IBM PC version of the USGS MODFLOW code was constructed to simulate the ground water flow beneath an industrial site in the central Midwest. A detailed three-dimensional...

Small Diameter Gravity and Pressure Sewers
In communities with low population density or physical features that make conventional gravity sewers inordinately expensive, alternative sewer technologies can be significantly lower...

The `Down' of Top Down
The 800-space parking area for the Milwaukee Center was built in a four story deep basement of the building. In order to excavate the area without damaging two adjacent historic structures,...

Design for Variable Frequency Drive Applications
This paper presents fundamental design criteria used to evaluate the operational and economic feasibility of installing a variable frequency drive (VFD) on a petroleum products pipeline....

Infrastructure and Marketing in Water Resources
Marketing and infrastructure are two areas of growing interest and importance in engineering. Nearly every engineering discipline now uses some form of marketing to promote its products...

Control of Surge Pressures in Irrigation Systems
Excessively high or low pressure within an irrigation system can result in damage to pipelines, pumps, valves, and on-farm facilities. Frequently, these pressure variations are caused...
