    Water wicking up porous media and air humidity ?

    I see, thank you. I erroneously thought it was #3 since I supposed the greater surface area of porous particles could play a role into replacing water vapor content in air more efficiently than porous particles slightly closer to measuring point.

    Water wicking up porous media and air humidity ?

    Hello, I'd like to know which of these 3 example I sketched would have a steadier and higher air humidity at measuring point, assuming same conditions (except those illustrated as different, like porous media thickness and measuring point), water level and air turbulence within larger container...

    Pressure inside a plastic bottle filled with water and squeezed by X weight?

    I can't get my head around this (or maybe I just explained my question poorly): if one considers only the weight-bearing area as you suggest, wouldn't a smaller supporting area yield a higher pressure even if weight stays the same, something which doesn't make sense to me since I guess that...

    Pressure inside a plastic bottle filled with water and squeezed by X weight?

    I (perhaps wrongly) assumed that pressure inside a bottle with a weight sitting on top should be higher than pressure inside a bottle with no weight on? Here's a sketch I did

    Pressure inside a plastic bottle filled with water and squeezed by X weight?

    I have this same question. Could the internal pressure be approximated to Force/Surface, so (mass*g)/surface area of a bottle? How inaccurate would this be? Thank you

    Capillary action speed formula?

    Thank you so much, it was exactly what I was looking for! :)

    Capillary action speed formula?

    Hi, I was looking for a formula to describe capillary action speed in a medium. On wikipedia (https://en.wikipedia.org/wiki/Capillary_action) I came across a formula which describes the cumulative volume of a liquid drawn by capillary action after time t where V is cumulative volume, A is...
