Conversion of solar energy to mechanical power through the use of
thermostatic bimetals and linear Fresnel lenses was found to be both
theoretically and experimentally feasible. Using linear Fresnel lenses
to concentrate sunlight on bimetallic coils caused a simple sun powered
motor to produce rotational shaft power. However, continuous rotational...
Recycling of water in aquaculture facilities is used to minimize the amount of energy or tempered water required to control water temperatures. The rate of heat exchange between the water and the environment can be an important variable in the design, management, and economic analysis of a recycle system. A...
A helically flighted rotating tube for concentrating dairy and
swine manure solids was developed and evaluated. The solids removal
and concentration factor values were measured with beet pulp,
dairy manure arid swine manure slurries at different influent flow
rates and suspended solids concentrations. A method of estimating
the performance of...
The development of the energy crisis has caused the
use of depletable energy resources to be monitored quite
closely in the United States. Within the agricultural
sector, irrigation is a large user of energy, with the
potential of using many times more energy than all other
agricultural field operations. A...
The occurrence of relatively less permeable soil underlying a
relatively more permeable and shallow soil profile is widespread in
the Willamette Valley Region of Oregon. Recognizing that an understanding
of the water transport process in such a situation would
provide reliable criteria for designing a drainage system has led to...
