Take two identical plastic bottles of equal size and shape. Pour water in to the bottle and concentrated saline water in other (height of the liquid level is same in both the bottles). Make a hole at the side wall close to the bottom of both the bottles. Which liquid is flowing out at a faster rate faster and why?

Answer:
Explanation: Given the case, the bottle with just water will have the tendency to leave the container quickly. This is because the viscosity of the concentrated saline solution is very high when compared to the previous liquid, and as we know, that the rate of flow of a fluid is directly proportional to the viscosity.
Also it is to be noted that this is the condition when the bottle is kept open from it's neck's end so as to allow the air inlet to avoid vacuum formation which might lead to the stopping of the flow.
