This "calculator" is provided for comparison purposes only, and the resulting pressure drop can be dramatically different in actual field conditions.
Note that the pressure drop calculated above is based on liquid media with the specific gravity of water (1.0) and the viscosity of water (1.0 centistoke). Even if your liquid has the same properties as water, other factors can impact the actual pressure drop.
The results above and the formulas provided by Plast-O-Matic Valves, Inc. are offered only for comparing the characteristics of thermoplastic valves, and are not for determining actual performance or for system design.
If you would like to determine other aspects of the pressure drop equation, for instance: What is the minimum Cv that will result in no more than a 10 psi pressure drop at 20 GPM? or, for instance, How much flow do I need to have less than 3 psi pressure drop with a .8 Cv?, your best bet is to use the actual formulas, which are shown here, or described in detail on our pressure loss and flow equation page. Even if you have used the calculator above, you will likely find the information on this link helpful.
