H is the height of the fluid column in ‘m’Ī swimmer experiences more pressure as he goes deeper underwater because of the more and more weight on the top as well as the air above him. G is the acceleration due to gravity considered as 9.81 ms -2 P is the pressure exerted by the liquid in Nm -2 The formula used to calculate hydrostatic pressure is shown below: Hydrostatic Pressure at different depths Image Credit: wikipedia
The pressure of a liquid at rest at a certain depth due to gravitational force is known as Hydrostatic Pressure and hydrostatic pressure increases as the depth measured from the surface increases because of the increasing weight of the fluid exerts more downward force on the lower liquid layers. Hydrostatic Pressure Difference is specific measurement of liquid pressure above a vertical datum at different points or at different heights from the datum line. To determine the respiratory flow in medical devices, air flow blockages in different devices, clogged filter detection in extractor fans, air conditioner, exhaust ducts are the examples of applications where Pressure difference monitoring plays an important role. If a part of a pipeline gets clogged, there is a change in pressure which makes a change in Pressure Difference, an operator can easily detect the exact blockage point and clean the pipeline to ensure the smooth flow of the fluid.įor a maximum value of pressure difference, we may have to change the filter otherwise it may lead to damage or corrosion. Pressure Difference is continuously monitored in industries to know whether there is any clog or contaminates through a pipeline.
