Static pressure cannot be calculated. Since pressure itself is form of energy it is possible however to apply Bernoulli's principle to it. Bernoulli states that the total energy in a streamline flow always remains constant. This means:
Pressure energy 
+ 
Kinetic energy 
= 
Constant total energy 
Static Pressure 

Dynamic Pressure 


This theory can only be applied below 0.4 mach (300 kts cut off) where density changes due to compression of air will not occur.
Before we can continue it is necessary for you to understand what dynamic pressure is and how it relates to kinetic energy. Therefore the dynamic pressure where we'll continue.
