Clock Hand Lateral, A New Layout for Semi-Permanent Sprinkler Irrigation System

assessment of pressure variation effect along lateral pipes of hand-move sprinkler irrigation system on costs

according to the irrigation systems design standards, allowed pressure variation in lateral pipes is 20 percent. reasons for this rate selection, which since the 60's is performed, are not known. the increased changes in allowed pressure tubes to lateral pipes design, the increased sprinkling system required pressure and the increased nonuniform sprinkler distribution, so energy supply cos...

Clock-Routing Driven Layout Methodology for Semi-Synchronous Circuit Design

The most expensive part in modern VLSIs is the clockdistribution network where the clock is assumed to be distributed periodically and simultaneously. While, in the semi-synchronous system, the clock is assumed to be distributed periodically, but not necessarily simultaneously. In this framework, we propose a new design methodology which maximizes the performance of a circuit subject to the min...

Sprinkler Irrigation: a Voc Remediation Alternative

A sprinkler irrigation system was tested to assess its efficacy for volatilizing organic chemicals in pumped groundwater. In field tests involving the analysis of more than 250 samples collected from beneath a spray irrigation system, removal rates of ethylene dibromide (EDB), 1,1,2-trichloroethylene (TCE), 1,1,1-trichloroethane (TCA), and carbon tetrachloride (CT) in samplers placed 0.5 m abov...

Sprinkler and mist irrigation for cooling lettuce:effectiveness and economic cosideration

Sprinkler Irrigation as a VOC Separation and Disposal Method

Sprinkler irrigation is a common farming practice in those states where the semi-arid climate and lack of sufficient rainfall during critical growing periods necessitate the use of supplemental water. The source of most irrigation water is groundwater which can be contaminated with volatile organic compounds (VOCs). Since the groundwater may be the primary or only source of drinking water for a...
