Acoustic Flowmeter Prototype Evaluation Tests

Description: Summary: "Prototype tests of an acoustic flowmeter system were made in a 24-ftdiam power penstock at Oahe Dam to evaluate the system prior to permanent installation in the outlet works at Summersville Dam. Comparative discharge measurements included acoustic, penstock pressure-momentum (Gibson), turbine model test ratings, scroll-case pressure differential (Winter-Kennedy flowmeter), and surge tank volume changes. The acoustic flowmeter measurements were very consistent and many of the comparis… more

Colorimetry

Description: "The definition of color, as a characteristics of light, and the basic principles of its measurement are given. The reduction of spectrophotometric data to three chromaticity coordinates by means of the three-function CIE standard observer system for colorimetry is described. Various methods of direct colorimetry, and visual and photoelectric methods of colorimetry by differences from material standards are treated" (p. 1).

A Study of the Disposal of the Effluent From a Large Desalination Plant

Description: From Introduction and Summary and Conclusions: "The disposal of the effluents from large desalination plants has been studied for two years by the Dow Chemical Company and Texas A. & M. University under contract to the Office of Saline Water. Recommendations are presented on the type, frequency, and intensity of pre-plant oceanographic and biological surveys and of post-plant monitoring and verification surveys."

Investigation of Membrane Stack Resistance Increase With a Natural Brackish Water

Description: From Introduction: "An investigation was undertaken by the Bureau of Reclamation to identify the cause of causes of this problem with a particular brackish water. The resistance increase of is of great concern principally because of the increase in power consumption that ultimately contributes to a higher cost for product water. Reports show that membrane stack resistance has increased as much as 200 percent over period of several days."
