Removing Water from Fixed Volume
I have a fixed volume inside a tank that when it warms up from freezing, residual water collects inside. I'm trying to remove this water by using a store bought dehumidifier. My plan is to put the dehumidifier inside a box, and seal it to the opening of the tank. Piping the removed water outside of the box.
I know from measuring the relative humidity inside I can estimate the amount of water that has collected inside my known fixed volume.
What I'd like to do is find the optimum pressure and temperature so that the water content is removed in the most efficient manner, ie quickest!
My gut is telling me I need to slightly reduce the pressure inside and raise the temperature to have the most effective dehumidifying effect.
Can anyone help on the relationship between pressure, temperature and humidity?
