One of his more popular discoveries is known as the Bernoulli Principle. This principle states that an increase in a fluid's speed decreases its pressure. If this is true, and we know it is, then the opposite must also be true: that a decrease in a fluid's speed increases its pressure. This principle applies to both the lifting of a wing on an airplane, as well as the lifting of a cartridge valve poppet. | ![](http://www.hydraforce.com/HFinsider/Bernoulli/Dan_Bernoulli.jpg) | | --- | --- | [Read More](https://info.hydraforce.com/hydraforceinsiderblog/bid/36656/Solenoid-Valves-and-Daniel-Bernoulli-Friend-or-Foe) 0 Comments [Click here to read/write comments](https://info.hydraforce.com/hydraforceinsiderblog/bid/36656/Solenoid-Valves-and-Daniel-Bernoulli-Friend-or-Foe#comments-listing) Tags: [cartridge valves](https://info.hydraforce.com/hydraforceinsiderblog/topic/cartridge-valves), [solenoid operated four way valves](https://info.hydraforce.com/hydraforceinsiderblog/topic/solenoid-operated-four-way-valves), [Bernoulli Principle](https://info.hydraforce.com/hydraforceinsiderblog/topic/bernoulli-principle), [cartridge valve poppet](https://info.hydraforce.com/hydraforceinsiderblog/topic/cartridge-valve-poppet), [HydraForce](https://info.hydraforce.com/hydraforceinsiderblog/topic/hydraforce), [solenoid operated three way valves](https://info.hydraforce.com/hydraforceinsiderblog/topic/solenoid-operated-three-way-valves), [solenoid-operated direct-acting spool valves](https://info.hydraforce.com/hydraforceinsiderblog/topic/solenoid-operated-direct-acting-spool-valves), [spool-type cartridge valves](https://info.hydraforce.com/hydraforceinsiderblog/topic/spool-type-cartridge-valves), [solenoid operated five way valves](https://info.hydraforce.com/hydraforceinsiderblog/topic/solenoid-operated-five-way-valves) [All posts](https://info.hydraforce.com/hydraforceinsiderblog/all) ### Subscribe by Email ### Other related info [![Sign up for Product news.](https://info.hydraforce.com/hs-fs/images/C--Documents%20and%20Settings-dp2-Desktop-Email-Signup-resized-156.jpg?width=171&height=72&name=C--Documents%20and%20Settings-dp2-Desktop-Email-Signup-resized-156.jpg)](https://info.hydraforce.com/HydraForceProductUpdates/) [![describe the image](https://info.hydraforce.com/hs-fs/images/k--sales-training-image%20library-request%20a%20catalog_2-resized-156.jpg?width=172&height=152&name=k--sales-training-image%20library-request%20a%20catalog_2-resized-156.jpg)](http://www.hydraforceleads.com/form/catalogForm.php) [![describe the image](https://info.hydraforce.com/hs-fs/images/K--SALES-TRAINING-Image%20Library-Download%20a%20copy%20of%20i-Design-resized-156.jpg?width=176&height=152&name=K--SALES-TRAINING-Image%20Library-Download%20a%20copy%20of%20i-Design-resized-156.jpg)](https://info.hydraforce.com/download-your-free-copy-of-i-design-v3-today/) [![K SALES TRAINING Image Library Custom Manifold Consultation resized 156](https://info.hydraforce.com/hs-fs/images/K--SALES-TRAINING-Image%20Library-Custom%20Manifold%20Consultation-resized-156.jpg?width=175&height=145&name=K--SALES-TRAINING-Image%20Library-Custom%20Manifold%20Consultation-resized-156.jpg)](https://info.hydraforce.com/Free-Custom-Circuit-Consultation/) ### Follow Me ### News Ticker **[Click Here ](http://www.hydraforce.com/News/News_tickr.htm)to see the latest HydraForce News.** ### Latest Posts ### Posts by category - [cartridge valves (25)](https://info.hydraforce.com/hydraforceinsiderblog/topic/cartridge-valves) - [proportional valves (11)](https://info.hydraforce.com/hydraforceinsiderblog/topic/proportional-valves) - [pressure control valve (8)](https://info.hydraforce.com/hydraforceinsiderblog/topic/pressure-control-valve) - [HydraForce (7)](https://info.hydraforce.com/hydraforceinsiderblog/topic/hydraforce) - [manifold design (7)](https://info.hydraforce.com/hydraforceinsiderblog/topic/manifold-design) ### OTHER RELATED INFO [![describe the image](https://info.hydraforce.com/hs-fs/images/k--sales-training-image%20library-request%20a%20catalog_2-resized-156.jpg?width=172&height=152&name=k--sales-training-image%20library-request%20a%20catalog_2-resized-156.jpg)](http://www.hydraforceleads.com/form/catalogForm.php) [![describe the image](https://info.hydraforce.com/hs-fs/images/K--SALES-TRAINING-Image%20Library-Download%20a%20copy%20of%20i-Design-resized-156.jpg?width=176&height=152&name=K--SALES-TRAINING-Image%20Library-Download%20a%20copy%20of%20i-Design-resized-156.jpg)](https://info.hydraforce.com/download-your-free-copy-of-i-design-v3-today/) [![K SALES TRAINING Image Library Custom Manifold Consultation resized 156](https://info.hydraforce.com/hs-fs/images/K--SALES-TRAINING-Image%20Library-Custom%20Manifold%20Consultation-resized-156.jpg?width=175&height=145&name=K--SALES-TRAINING-Image%20Library-Custom%20Manifold%20Consultation-resized-156.jpg)](https://info.hydraforce.com/Free-Custom-Circuit-Consultation/)
