Do anyone recognizes the following Gas Flow formula (for air here)?
W (lbs/sec) = 6.30*Cd* (d^2) *P1 /[(53.34*T)^0.5] * {3.5[(P2/P1)^1.429 - (P2/P1)^1.714]}^0.5
I would appreciate someone can point me to the source.
I understand one from "Crane":
qm' (SCFM) = 678 *Y *(d1^2)* C...

The 17-4 part was heat treated to H1075. Because conformity problem, could we reheat treated to H1075 again? Will this affect the material properties (strength, fatigue, toughness)? Thank you.
