I am trying to figure out how much vacuum would be drawn on a tank of hydrocarbon that is blocked in. The scenario is the tank is ~90% full and has been isolated. The tank normally has a vent but in this case the vent is also obstructed. I am just interested to see what vacuum the tank would experience due to cooling from say 90F to 70F. I did a quick calculation using the ideal gas law (assuming the liquid stays a constant volume and only the vapor changes) and varying the pressure with the change in temperature and got a reasonable answer of ~14"wc. Does this approach make sense? Is there a better way to look at it?
