Using energy balance and heat transfer equation, temperatures of argon exiting ullage space have been estimated for Micro-Boone. For the 3 cases under consideration, the temperatures are 178K, 176K and 150K. Note, this study is not applicable to nozzles and feedthrough on the vessel where temperautres are higher because top of nozzles is near ambient temperature. Temperature profile inside nozzles will be investigated in another note.

Notes and Changes:
This documentation is submitted under WBS 1-10. However, it is also of interest to subjects such as liquid argon heat transfer, thermal evaluation of feedthrough and outgassing study.
