What is the difference between Stagnation & Static Pressure

What is the difference between Stagnation & Static Pressure


The Stagnation Pressure is the sum of the Static Pressure and Velocity Pressure. In the example below, we can see that the Stagnation Pressure at the pipe inlet is 111457.5 Pa a. 

We can also see that this is the sum of the In Static Pressure and In Velocity Pressure as follows:

Stagnation Pressure = 109037.5 + 2420.0 = 111457.5 Pa a.
