WATER GAIN BEHAVIOR OF OUTDOOR CLOSED STRUCTURES

Abstract

A model of the water gain of empty structures stored in the open is derived. Using this model and a modified Monte Carlo procedure, a statistical analysis is made of probable water gains at 12 stations by enclosures which are free breathing and which have check valves set at +2 -1, +1 -1, +1 -1/2 and +1/ 2 -1/2 psig. It is concluded that a breather charge of one ounce per cubic foot should give about six months storage life anywhere in the world, assuming adequate container drawdown. Even the +1/2 -1/2 psig valve required no additional desiccant although it might be expected to breathe as much as 38 times per year at Los Vegas, Nevada with 2 sigma confidence. The least pressure-vacuum spread which will not adversely affect a reasonable storage life was not discovered.
