Total (Stagnation) Property - A point in a flow field in which the flow is brought to rest is called a stagnation point, and properties at that point are called total (stagnation) properties. Thus in contrast to static properties, measurements of stagnation properties require that the flow be brought to rest with respect to the observer's instruments. Total properties include both static and dynamic effects. For example, the total pressure equals the static pressure plus the dynamic pressure:
Ptotal = Pstatic + r*Vē/2g
Static Property - Static properties are those that would be measured if one could travel with the fluid at its exact velocity (in this case the relative velocity between the observer and the fluid would zero – hence the term "static"). Static properties do not contain dynamic effects.
The figure below illustrates the difference between static and total pressure.
