Hurri -
However in the interest of simplicity which I fancy truly exists here seeing: M= P/S
- cannot see where you get that from? As you can see the Machmeter does not simply " measure the ratio of dynamic to static pressure" in real terms..
In post #13 you were given
M = SQR (5 X (Qc/Ps + 1)^((Y-1)/Y) - 1) which is where your "P/S" sits.
"P" is 'derived' from "Total pressure"
"S" " " " "Static Pressure"
What we cannot fathom is why the need to go to the
very root of this equation? Why do you need to know please? Why does this not satisfy your thirst for knowledge? Have the search engines failed to answer?
What does "can you show me how P/S is true," mean?
I'm looking for the several equations which when manipulated and simplified give the relation ship.
- I would observe you have them!
