 Title: Fluid pressure (levels) Post by: ahmedelshfie on April 30, 2010, 07:21:40 pm This applet created by prof HwangModified by AhmedOriginal project Fluid pressure (levels) (http://www.phy.ntnu.edu.tw/ntnujava/index.php?topic=1575.0)There are three different liquids in the pipe, with density d1,d,d2The level will be adjusted due to different in pressure in two sides of the pipe.It will reachs equilibrium when the pressure are equal at the buttom.  Title: Re: Fluid pressure (levels) Post by: ahmedelshfie on May 04, 2010, 02:24:59 am Images from http://en.wikipedia.org/wiki/Fluid_statics Title: Re: Fluid pressure (levels) Post by: ahmedelshfie on October 23, 2010, 11:46:52 pm Fluid pressure is the pressure at some point within a fluid, such as water or air.Fluid pressure occurs in one of two situations:   1. an open condition, such as the ocean, a swimming pool, or the atmosphere; or   2. a closed condition, such as a water line or a gas line.Pressure in open conditions usually can be approximated as the pressure in "static" or non-moving conditions (even in the ocean where there are waves and currents), because the motions create only negligible changes in the pressure. Such conditions conform with principles of fluid statics. The pressure at any given point of a non-moving (static) fluid is called the hydrostatic pressure.Closed bodies of fluid are either "static," when the fluid is not moving, or "dynamic," when the fluid can move as in either a pipe or by compressing an air gap in a closed container. The pressure in closed conditions conforms with the principles of fluid dynamics.The concepts of fluid pressure are predominantly attributed to the discoveries of Blaise Pascal and Daniel Bernoulli.Data from  http://en.wikipedia.org/wiki/Fluid_pressure(http://www.phy.ntnu.edu.tw/ntnujava/index.php?action=dlattach;topic=1621.0;attach=2410)
