Cook Plant preoperational studies, 1969 / John C. Ayers ... [et al.].

on the staff, and with the staff lying horizontally on the deck in the open air,
this thermistor read the same temperature as the others,
As these micrometeorological data werefurther contemplated there came to
light the possibility that warmer air next to the warm plume water need not be
expected. The transfer of sensible heat from plume water to air may be
demonstrable only as less rapid vertical cooling in the bottom of the air column
over the plume water, in comparison to that in the bottom of the air column over
ambient lake water outside the plume. This will be assessed in 1970 by floats
of the air temperature staff in lines transverse to plume axes. From these
temperature readings the rates of vertical cooling in the bottom of the air
column over the plume may be compared to cooling rates in the bottom of the air
column at positions outside the plume. Such experiments will at least answer
our lingering doubts as to whether the present Yellow Springs thermistors are
sufficiently sensitive to provide answers to this type of question.
On 30 June in the outer end of the outfall channel at Waukegan we tried to
use a Bendix Model 566-3 Psychron aspirated psychrometer to determine whether
local differences in relative humidity could be found near warm plume water. The
instrument ventilates its wet and dry bulbs electrically and may be sensitive
enough for the purpose, but it requires visual readings of the thermometers. The
tallest man on the ship was able, by lying down, kneeling, stooping, standing
erect, and standing upon a box, to read the two thermometers at each foot of
altitude from 1 through 6 feet above the water. The results are tabulated below:
Height Dry Bulb Wet Bulb dT Relative Humidity
1 ft 22.0~C 20.5~C 1.5~C 87%
2 22.0 20.3 1.7 86
3 21.7 20.0 1.7 86
4 21.9 20.2 1.7 86
5 22.0 20.5 1.5 87
