The relationship between air flow and static pressure of a fan is shown in the graph above. As you can see, air flow and static pressure have a negative correlation. When air flow increases, static pressure decreases; and when static pressure increases, air flow decreases. The 3 points depict possible scenarios where the fan will perform.

Pressure and velocity have an inverse relation an example pumps are used to to increase the velocity of the fluids in case when water flows from a river to a canal the cross sectional area of the flowing water decreases and the velocity of the water increases the question is from where this energy comes the answer is it follows the law of ...

After more than 25 years in the compressed air industry, it still amazes me that many plant personnel and even those who sell compressed air products for a living don't fully understand the relationship between flow, or volume (cfm), and pressure (psig). Walk into many body shops or small manufacturing plants, and you will find the compressor …

In this article, we will consider the key concepts of pressure and flow and how they apply to hydraulic systems – as it is the pressure and flow which enable work and motion to be accomplished. ... This provides a detailed explanation of the relationship between pressure and force and how they are used within a hydraulic system.

They aren't. I often hear the complaint that a pump isn't putting out as much pressure as it should, implying that the pump is supposed to deliver pressure. A common assumption is that if the pressure is low, the pump must be bad. This is not the case. The pump doesn't pump pressure. The pump delivers a rate of flow.
