keyword=pressure drops due to temperature decreasing
The hydrogen loop connected to a large tank outside the hall. When
temperature changes (day-night), pressure will change accordingly. It is
more obvious today due to large temperature change (low~50F, high ~80F).
The 24-hour pressure change follows the temperature change well.
