Estimating The Payback For An Electrical Vfd (Variable Frequency Drive) Application In A Pumping Plant Which Presently Spills Excess Pumpage, Charles M. Burt
Estimating The Payback For An Electrical Vfd (Variable Frequency Drive) Application In A Pumping Plant Which Presently Spills Excess Pumpage, Charles M. Burt
BioResource and Agricultural Engineering
This report includes equations and tips for pump selection criteria and estimating the annual KW-hr savings for a VFD installation, including the maximum potential savings and the approximate amount of KW-hr that would have been consumed if one pump had been converted to VFD.
Monolithic Concrete Irrigation Pipe, Charles M. Burt, John M. Wegener
Monolithic Concrete Irrigation Pipe, Charles M. Burt, John M. Wegener
BioResource and Agricultural Engineering
Monolithic concrete pipe (also known as "Cast-in-Place Concrete Pipe" (CIPCP) or Cast-In-Place Pipe (CIPP)) is widely used in some regions for purposes such as storm, sewer, or irrigation pipelines. The earliest use of CIPCP was in 1922 in the Turlock Irrigation District of California. It is reported by The Sierra Group (Sierra, 1991) that there are over 15 million linear feet (4.6 million linear meters) of CIPCP under various applications. Nevertheless, many irrigation engineers, especially outside the U.S., are unaware of CIPCP. Monolithic concrete irrigation pipe is seldom mentioned in irrigation design literature. This paper has been written to familiarize …
Grassland Basin Irrigation And Drainage Study, Stuart W. Styles, Dennis Westcot, Dr. Charles M. Burt, Ross Steensen
Grassland Basin Irrigation And Drainage Study, Stuart W. Styles, Dennis Westcot, Dr. Charles M. Burt, Ross Steensen
BioResource and Agricultural Engineering
This paper summarizes a project that analyzed the district irrigation efficiency for six subareas of the Grassland Basin roughly representing 80,000 acres on the west side of the San Joaquin Valley near Firebaugh, California. The objectives of this project were to: • Determine the district irrigation efficiency for the six subareas. • Update district drainage policies and water reuse. • Update the geographical information system (GIS). • Perform a pre-plant irrigation efficiency analysis. • Establish a relationship between the drainage volumes and the district irrigation efficiency. • Determine the maximum district irrigation efficiency attainable. • Determine the impact of optimizing …
Evaluating Strength & Energy Requirements For Workers Picking Vegetables, R. A. Cavaletto, J. Miles, J. Meyers, J. Mehlschau
Evaluating Strength & Energy Requirements For Workers Picking Vegetables, R. A. Cavaletto, J. Miles, J. Meyers, J. Mehlschau
BioResource and Agricultural Engineering
The paper discusses the need to obtain field data to evaluate the strength and energy requirements for workers picking a variety of vegetables. This information is central to the evaluation of hazards related to repetitive motion, excessive stress, and fatigue. Results can be used to select activities which should be targeted for future engineering design projects. Preliminary data from a commercial broccoli harvesting operation is included.
