Keep it full of water. Otherwise, put gravel below and around the pool before it is built, then install a shaft and put in a sump pump. make sure the sump pump is on whenever the pool is to be empty.
The pressure inside the lungs decreases as the ribcage moves out and up. Air from outside basically gets pushed in by other air molecules due to the pressure gradient (air moves from a high pressure to a low pressure)
It is pushed by the water pressure in the system.
Yes, but weakly (i.e. low pressure).
When molecules of air are pushed together, they form an area of high pressure which is called compression. If the compression is cyclonic, it is called a node.
Pressure effected by the volume of substance being pushed through. For instance, the longer the hose, the more water being pushed through=greater pressure. The shorter the distance the less water being pushed through=less pressure.
what is the difference between thrust and pressure?
When molecules of air are pushed together, they form an area of high pressure which is called compression. If the compression is cyclonic, it is called a node.
Pressure is important in HPLC to maintain the flow rate of the mobile phase through the column, which is necessary for efficient separation of compounds. The pressure also helps to ensure that the analytes are pushed through the column at a constant rate, resulting in consistent and reliable chromatographic results. Adequate pressure is needed to overcome frictional forces within the system and to prevent band broadening.
Googles or long sleeves
compression
Not necessarily. "Pushed" can have both negative and positive connotations depending on the context in which it is used. It can imply pressure and force, but it can also suggest motivation and drive.
Why would they want me to answer the question if I'm the one asking it?! pressure is any energy pushed on the body gravity is a good example
