week 1 Flashcards
the ability of a device or mechanism to do a
specific amount of work over a period of time.
Power –
a unit of power commonly use in the farm to
indicate the work output of humans, draft animals, and
mechanical prime movers
Horsepower –
– the rate at which a machine or an
implement can cover a field while performing its
intended function.
field capacity
is driven by solar
radiation and the rotation of the earth
- Global wind circulation
in the northern hemisphere
Northeast trade winds
in the southern hemisphere
Southeast trade winds
is a machine that convert the
kinetic energy of the wind to mechanical
power for pumping water.
Windpump
it does not cause pollution. No burning of fuel
is required
clean
supply of wind is adequate throughout
the year.
Abundant
No cost on fuel and minimum labor for
operation is required. Technology can be localized to
reduce investment cost.
Cheap –
Wind is continuously available and will
never run
out.
Sustainable –
it is equipped with safety devices that protect
the machine from strong wind.
safe
– It creates employment and development
of local industry.
Economic
– It can be used for mechanical
as well as for power generation to reduce cost of
production in agriculture and other industries
Varied Applications
applicable or adoptable only in areas
with wind speed of 3 mps or higher.
