PLSS Condensate Transfer Assembly
The PLSS Condensate Transfer Assembly accommodates a maximum of 5190
cc of liquid condensate. The maximum value of condensate fluid from
a single PLSS discharge shall be 4400 cc of which a maximum of 865
cc shall be liquid.
The PLSS Condensate Transfer Assembly operational temperature is 35°F
to 135°F. The relief valve cracking pressure is 2.1 to 2.9 psid.
The full open pressure is 3.8 psid.
The rate of flow of condensate from the PLSS to the PLSS Condensate
Transfer Assembly is from 0 cc/sec to i00 cc/sec. The maximum
flow rate for "all water" transfer is 25 cc/sec. The maximum flow
rate for all gas is i00 cc/sec.
Thermal Variations for the MESA

from the MESA (NASA DATA SOURCE)

Thermal Response of the Lunar Surface Color TV Camera (NASA DATA SOURCE)
See SODB Volume VII (GCTA) for TV Camera Operation and Performance data.
4.2.7 Crew Heat Storage and Temperature Tolerance Limits
Heat storage should be limited to _300 Btu. Above 300 Btu, the perfor-
mance of tasks of mental complexity or high physical demand is sharply
reduced. Below -300 Btu, shivering is continuous and very distracting
and likely to severely limit performance. Figure 4.2-1 indicates these
areas as the limited tolerance hot and cold zones. Between these zones
tolerance is not time limited.
