- Predict the probable operating mode of this system
In June, during the longest day of the year, the system will deliver up to 5.6 million gal-
lons (21,196 m

) over a 9.5-h period. Future provisions for energy storage can be made, if
needed.
Related Calculations. Solar-powered pumps can have numerous applications
beyond irrigation. Such applications could include domestic water pumping and storage,
ornamental fountain water pumping and recirculation, laundry wash water, etc. The
whole key to successful solar power for pumps is selecting a suitable application. With
the information presented in this procedure the designer can check the applicability and
economic justification of proposed future designs.
In today's environmentally-conscious design world, the refrigerant must be carefully
chosen so it is acceptable from both an ozone-depletion and from a thermodynamic stand-
point: Banned refrigerants should not, of course, be used, even if attractive from a ther-
modynamic standpoint.
This procedure is the work of the editorial staff of Product Engineering magazine re-
porting on the work of Battelle Memorial Institute and the Northwestern Mutual Life In-
surance Co. The installation described is located at MMLF s GiIa River Ranch, southwest
of Phoenix AZ. SI values were added by the handbook editor.
