I was too bored and I started to wonder about the properties/behavior of fluids. air in particular. I was in the back seat of the bus on the drivers side or the silencer side. Government automobiles are the worst form of pollution. I was thinking where does all this smoke go when the bus travels at a faster rate. I mean at slower speeds we can see the smoke but at higher speed ??? As soon as i got access to the internet I started digging for details. There are very few articles explaining displacement properties of air. But the behavior of water has been explained very clearly. I took the same concept and applied it to air. Considering air is lighter and less cohesive than water, it is easier to move and so displaces a lot. Turns out a greater part of the smoke is redirected to my face(The passenger on the back seat). Also if it is after a rain the air is dust free and humid(still lighter- lower part of the atmosphere has O2 (Atomic weight-32) replaced by H2O (Atomic weight-18)) means the smoke is on your face even at lower speed.
Following this I started to wonder about the train and the occasional water droplets on our face (foot board passengers) even after the rain stops. Roughly calculating I got the result that those water drops can be the stagnant water on the roof or the flush of a toilet. Also I was assuming the old fashioned trains where there was gap between the compartments.
But remember that I am basing this on the behavior of homogeneous fluids and our test cases are all heterogeneous fluids. Which means this whole thing I am saying MAY BE wrong.
Also remember the words of bajji vaayan MAY BE also means MAY NOT BE.
