How to Convert Differential Pressure to Flow | Sciencing

For example, using Bernoulli's equation, it is possible to relate the differential pressure of a fluid (i.e., the difference in pressure of the fluid between two different points) with the flow of the fluid, which is important if you would like to measure how much fluid flows over a given amount of time.

Jun 18, 2010 · It seems Rod's final word came right at the start: in his title. "It is probable that atmospheric scientists were wrong about CFCs". Like an "anti" nuclear protestor at a public meeting arguing that radiation is much more dangerous than radiation scientists have discovered, Rod accepts no evidence as valid except that which reinforces his beliefs.
