This study was prompted by the need for improving the efficiency of irrigation
systems at the Oregon South coastal areas. Accurate information about
evapotranspiration (ET) rates is essential for maximizing the efficiency of irrigation
systems....

Centrifugal irrigation pumps discharge fluids at high velocities that must be slowed
to minimize energy losses due to friction. Pipe expansions make the transition to larger
pipes associated with slower velocities. Expansions convert the upstream...

The main purpose for irrigating is to supply needed water for
crops. Plant growth is dependent on photosynthesis. While the plant
exchanges gases with the air for photosynthesis, some water
evaporates. Water is taken up from the soil by plant...
