| snow gun (snow maker) |
apparatus that can produce
and shoot artificial snow over a long distance; used to make or improve a ski
area |
| | |
| snubber pulsation suppressor |
restrictor placed
in the liquid or vapor line to suppress pulsating or fluctuating pressures. |
| | |
| soda fountain |
service counter
containing a water cooler, a water carbonator, a refrigerated compartment for
syrups and diced fruit, and a low-temperature compartment for ice cream. |
| | |
| soft soldering |
hot joining
operation in which the melting temperature of the filler metal is lower than
800°F (450°C). |
| | |
| softening point |
temperature at
which a solid loses rigidity or consistency in a standardized test procedure. |
| | |
| solar colector instantaneous efficiency |
ratio of the
energy removed by the transfer fluid per unit of collector area to the total
solar radiation incident on the collector per unit area (aperture or gross)
during a test period for which the condition of the test corresponds to the
steady state or quasi-steady state. |
| | |
| solar collector |
device designed to
absorb incident solar radiation and to transfer the energy to a fluid passing
through it. |
| | |
| solar collector absorber | part of the solar
collector that receives the incident radiation energy and transforms it into
thermal energy. It may possess a surface through which energy is transmitted to
the transfer fluid; however, the transfer fluid itself can be the absorber |
| | |
| solar collector aperture area |
maximum projected area of
a solar collector through which the unconcentrated solar radiant energy is
admitted |
| | |
| solar collector cover | material covering the aperture
to provide thermal and environmental protection |
