Microcomputer-Based Index Testing of Hydroturbines
A computer-assisted system for performing index test on hydroturbines is described. This system allows for more rapid and accurate index testing of hydroturbines than has previously been...

Experimental Study of the Cross-Flow-Turbine
The performance of the Cross-Flow or Banki Turbine (C-F-T) was studied experimentally by varying the number of blades, the runner diameter, and the nozzle entry arc under flow/head variations....

Lessons Learned from First Impulse Turbine Installation in the U.S. Mining Industry
The paper discusses a research study to recover energy from service or cooling water brought into deep mines. The test site was the Luck Friday Mine, owned and operated by the Hecla Mining...

Turbine Efficiency Loss Associated with Draft Tube Aeration
Draft tube aeration is one method for improving the dissolved oxygen content of hydroelectric discharge. A simple analytical procedure is presented for estimating the loss in turbine efficiency...

The PowerBarge Hydroelectric Plant
Following an account of the need for such an approach, the PowerBarge hydroelectric plant design concept is described as a fully floating system consisting of an Intake Barge, Siphon Penstock,...

Libby Rereg's Combined Spillway and Powerhouse
The existing powerhouse at Libby Dam, located near Libby, Montana has four generating units for a total of 420 MW. Provisions have been made which will allow doubling the plant rating...

Update on Impact Effects in Nuclear Plants Part I?Overview and Need for Integrated Approach
In this paper, an ASCE working group on impact effects in nuclear plants updates the review of this technology contained in a five-year-old ASCE report. In Part I, an overview is given...

Field Flow Measurement of Hydro-Turbine Efficiency
Performance tests were conducted at Great Northern Paper (GNP) Company's Weldon Hydroelectric Station. The purpose of the tests was to calibrate the Winter-Kennedy taps and...

Sedimentation in Small Hydropower Reservoirs
Small-scale hydropower projects, which usually include reservoirs of limited size, may inherently incorporate severe sedimentation problems. The ratio of reservoir volume to sediment inflow...

Computer-Aided Preliminary Optimization Model for Low-Head Micro-Hydro Installations
It is demonstrated with applications, that the use of a computer-aided preliminary optimization model can help evaluate the overall technical and economic characteristics of low-head hydro...

Walden Hydroelectric Power Project
The Wallkill River at Walden, New York, produced hydroelectric power from 1909 to 1966. Using turbines dating back to the original hydroelectric development, the Walden hydroelectric station...

Superhydro
In 1986, when its six turbine/pump-generator/motor units will be in operation, the Bath County Pumped Storage Hydroelectric Project in Virginia will be the world's largest....

Hydro Recovery
The largest water utility in southern California is discovering that it makes sense to generate electricity too. During the past four years, the Metropolitan Water District of Southern...

Electricity from the Sea
In Hawaii, the state, Lockheed Space and Missile Co. and Dillingham Corp. have conceived, designed and built the first prototype ocean thermal energy conversion plant. OTEC uses the 40�F...

Automatic Steam Gathering Reduces Emissions at The Geysers
At the site of The Geysers, America's only geothermal power plant and the largest such plant in the world, the first completely computerized steam gathering system has been...

Symposium on Reaeration Research
Proceedings of the Hydraulics Division Specialty Conference, held in Gatlinburg, Tennessee, October 28-30, 1975. Sponsored by the Hydraulics Division of the American Society of Civil Engineers....

Peaking Power from Stored Air
