So the rate at which the water level drops is independent of the shape of the receptacle.
No matter what differences between the shapes of two containers, as long as the initial height of liquid is the same both will have their content fully evaporated in the same amount of time.
Interesting!
I suppose when thinking about it it makes sense since each area unit will cause the column of water beneath it to decrease at a rate independent of all other area units.

Thanks! 😀
