Bie6300 - Irrigation & Conveyance Control Systems, Spring 2004, Gary P. Merkley Jan 2004

Bie6300 - Irrigation & Conveyance Control Systems, Spring 2004, Gary P. Merkley

Biological and Irrigation Engineering - OCW

This is a course regarding measurement of flow rates and water levels. Calibration, design, and selection of open-channel flow measurement structures. Design of irrigation conveyance and distribution system infrastructure.


Bie6810 - Biochemical Engineering, Spring 2004, Ron Sims Jan 2004

Bie6810 - Biochemical Engineering, Spring 2004, Ron Sims

Biological and Irrigation Engineering - OCW

Biochemical processes, thermodynamics, and kinetics are used in the application of engineering principles to analyze, design, and develop processes using biocatalysts. Processes covered in the course include those that are involved in the formation of desirable compounds and products or in the transformation, or destruction of unwanted or toxic substances.


Bie6150 - Surface Irrigation Design, Spring 2004, Wynn Walker Jan 2004

Bie6150 - Surface Irrigation Design, Spring 2004, Wynn Walker

Biological and Irrigation Engineering - OCW

This course was originally developed for the United States Department of Agriculture. It contains nearly 20 video lecture presentations with accompanying slides in English, Arabic, and French, an online textbook, homework assignments, and downloadable surface irrigation simulation software also developed by Dr. Walker. This course highlights design and evaluation of surface irrigation systems, field measurements for evaluating and improving uniformity and efficiency, simulation of surface systems, and land leveling computation and equipment. Note: The simulation software is designed to run on a PC only.


Kinetics Of Transesterification Of Soybean Oil, Hossein Noureddini, D Zhu Mar 1997

Kinetics Of Transesterification Of Soybean Oil, Hossein Noureddini, D Zhu

Papers in Biomaterials

Transesterification of soybean oil with methanol was investigated. Three stepwise and reversible reacttons are believed to occur. The effect of variations in mixing intensity (Reynolds number = 3,100 to 12,400) and temperature (30 to 70'CJ on the rate oireaction were studied while the molar ratio of alcohol to triglycerol (6:l) and the concentration of catalyst (0.20 wt% based on soybean oil) were held constant. The variations in mixing intensity appear to effect the reaction parallel to the variations in temperature. A reaction mechanism consisting of an initial mass transfer-controlled region followed by a kinetically controlled region is proposed. The experimental …
