curve (Figure 8.12). Notice that something was definitely wrong with the system for the month
of November.
8.7 Water PuMPing
Water pumping by windmills is an old technology. There have been a number of suggested changes
to the farm windmill; however, most have not been commercial. The electric-to-electric system
for pumping larger volumes of water for villages and small irrigation [16] has been designed and
prototypes have been tested. Now such systems are available in the commercial market. The perfor-
mance for water pumping can be estimated by a flow curve for water and a wind speed histogram to
estimate the amount of water pumped by month or year.
