I am aware I could also lower the tube into the tank, seal it, then lift it up, but this isn't viable for me as I won't have a deep enough tank to be able to get the water far enough up the tube.) experimental-physics pressure fluid-statics vacuum home-experim...
Learn how to find the gauge pressure in a constant density fluid at a certain depth, and see examples that walk through sample problems step-by-step for you to improve your physics knowledge and skills.

break boredom. This science video teaches you how to boil water at room temperature. Obviously this won't work in the normal conditions in which you boil water. But if you place the water in a vacuum, where the atmospheric vapor pressure is lowered, water can boil at a much lower ...
can be used to find an unknown boiling temperature for water. In this formula, BPcorr means boiling point at sea level, BPobs is the unknown temperature, and Pobs means the atmospheric pressure at the location. The value 760mmHg is standard atmospheric pressure in millimeters of mercury at ...
In the Flow of dry water chapter of Feynman lecture, this following point is written (see here): The law of hydrostatics, therefore, is that the stresses are always normal to any surface inside the fluid. The normal force per unit area is called pressure. From the fact ...
Echo Sounder: Sometimes, lakes or rivers are deeper than expected and become traps that will drown your engine. To avoid this problem, use the Echo Sounder, which displays the depth of the surrounding water. Drone: The perfect gadget to scout surroundings from the sky to detect some dangers ...
For instance, a water molecule is made from two hydrogen atoms and one oxygen atom bound together into a single unit. In nature, any atom you find will be one of 92 types of atoms, also known as elements. So every substance on Earth — metal, plastics, hair, clothing, leaves, glass ...
However, except for these ones, other factors can lead to water change its boiling point. Atmospheric Pressure When we boil water in a place with low air pressure and/or when the air is thin itself, it will take the liquid less time to reach the boiling point at high altitudes. ...
However, as you increase the initial radius of your stream, the water mass (~R^2) grows while the pressure gradient created by surface tension forces (~1/R) declines. That's why the cylinder will pretty quickly separates into multiple streams, and eventually into droplets.....
