Pressure in fluids |⚡ 3d animation | Class 9, Physics |

It is important to understand the term thrust first before understanding pressure. The force acting on a surface is known as the thrust. It has both direction and magnitude. The force exerted per unit area applied in a perpendicular direction to the object surface is known as pressure. This perpendicular force is known as thrust. Hence, pressure can also be defined as thrust per unit surface area. Fluid pressure is the pressure exerted by a fluid. For example, water (fluid) in a glass (container) exerts pressure in all directions, at all points.
Let's now define atmospheric pressure.The air in the earth's atmosphere exerts a force upon all the objects in the atmosphere and also on the earth. Atmospheric pressure can be defined as, the force exerted by the atmospheric air upon a unit area.

Very informative video, thanks. Do you have time to answer a question for me? I have a cylinder filled with water, There's a small hole in the top that I can open and close. There's a hole in the bottom that I can open and close, just to control whether or not water is released. If both holes are closed, obviously no water is released. If the cylinder is filled to the top and I open the bottom hole, no water is released until I open the hole at the top. If I open the top hole very briefly, some water is released but stops very quickly after I close the hole at the top. If the cylinder is only two-thirds full, the flow continues for a longer amount of time after I close the top hole. If it's one-third full, it takes an even longer time to stop flowing. Can you tell me why it works this way? I'd be most appreciative if you can answer this question. Thanks very much!

Due to variation in atmospheric pressure each time.
