Observing the Effect of Water Pressure

#pressure #properties #ngscience
Observe how water pressure affects a stream of water as it leaves a plastic bottle.

At greater amounts of pressure, the water streams from the bottle at a greater distance. This occurs as the water above exerts a force on the water below it due to its mass and the force of gravity.

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!

I have a question. Does the amount of pressure affects the amount of water coming out? Supposed all holes are exactly the same, does hole C release a greater amount of water than hole A? Thanks in advance

It means that if height increases inside fluid pressure is also increased
