Techniques For Improving Energy Efficiency At Water Supply Pumping Stations, Lindell Ormsbee, Thomas M. Walski, Donald V. Chase, Wayne W. Sharp

Civil and Environmental Engineering and Engineering Mechanics Faculty Publications

This report describes the application of methods presented in Engineer Technical Letter (ETL) "Energy Efficiency at Water Supply Pumping Stations'' to the Washington, DC, and vicinity water system.

Both the ETL and this report were prepared under the Water System Operation, Maintenance and Rehabilitation Work Unit (CWIS 31794) of the Water Supply and Conservation Research Program. The technical monitors for this program in the Office, Chief of Engineers, were Mr. James Ballif (DAEN-ECE-B) and Mr. Robert Daniel (DAEN-CWP-D). The work was conducted at the US Army Engineer (USAE) Waterways Experiment Station (WES), Vicksburg, Miss., and the University of Kentucky (UK) …

This document was prepared according to the 1986 edition of the AISI Specification for the Design of Cold-Formed Steel Structural Members. The selections of ϕ …

Design Of Automotive Structural Components Using High Strength Sheet Steels The Effect Of Strain Rate On Compressive Mechanical Properties Of Sheet Steels, Maher Kassar, Wei-Wen Yu

CCFSS Library (1939 - present)

INTRODUCTION Since May 1988, the research project on automotive components sponsored by American Iron and Steel Institute (AISI) at University of Missouri-Rolla (UMR) has been concentrated on a study of the effect of strain rate on mechanical properties of sheet steels and the structural behavior and strength of cold-formed steel members subject to impact loads. The results of the tensile dynamic mechanical properties of three selected sheet steels, in the virgin condition as well as for the steels subjected to different amount of cold stretchings, were estabiished in 1988 and early 1989. Details of the tension coupon tests were presented …

Logistics is an age old problem that has been the key to the greatest victories and defeats in history. Maritime support of wartime land campaigns as well as conflicts at sea, has been the answer to that problem even as far back in history as the ancient Greek Empire. Throughout the ages however the lesson that seems to be learned and relearned, the hard way, is that of logistic support. Today the United States is faced with what, to some seems to be an overwhelming problem in logistic support overseas, particularly in the maritime transportation and support arena. The U.S. …

Design Of Automotive Structural Components Using High Strength Sheet Steels The Effect Of Strain Rate On Mechanical Properties Of Sheet Steels, Maher Kassar, Wei-Wen Yu

CCFSS Library (1939 - present)

INTRODUCTION During recent years, automotive manufacturers have produced lighter vehicles for the purpose of achieving fuel economy. To accomplish the construction of such automobiles, high strength sheet steels with various yield strengths up to 190 ksi have been used for auto parts and structural components 1-9. In order to provide some technical assistance for the design of such high strength steels, the first edition of the "Guide for Preliminary Design of Sheet Steel Automotive Structural Components" was issued by American Iron and Steel Institute (AISI) in February 1981. 10 The use of the Guide was discussed by Errera at the …
