Hi, I don't even know if I'm in the right forum here. Maybe the physics one is more appropriate...

The problem that I have is more about the formula. Like I said, I try now to make a simulation about this process. The problem that I don't know what I should use for the length. Since the pipe is on one side closed, the length is time dependent. Either if I use Hagen-Poisuille or this formula...

Ok, maybe it's more like a pipe. The diameter is indeed 0.003m or 3mm. No, the water shouldn't be a problem. Since it's falling down, the temperature is increasing and there should be no condensation of the water. And it can only be used if there is no liquid water in the atmosphere (clouds). Or...

The I.D is 0.003m. The material can be neglected. Or we can assume that there is no adsorption of the air and also no permeation through the material and the material itself will be very smooth. There is of course diffusion within the air once the air is inside the capillary but at the moment we...

Hi everyone, I'm doing a simulation and need some help. A capillary which is closed on both ends with the length l (x=0 to x=l), with a radius R and the volume pi*R^2*l is dropped on a parachut at the time t=0 from a height h above ground. At t=0 the pressure inside the capillary is p_i0 (this...
