I've managed to buy a cylinder full of pure nitrogen with regulator and tubing. If I breathe it in will it kill me?
Let's say we have a vertical capillary tube with one of its ends in water. It has radius such that water rises up to a height of 5 cm. Now if we make a small hole at the height at 3 cm, then what will happen? Will the water be continuously flowing out of it or will the water not flow out of that hole that I made?
