In ISO 5167 standard, in the equation for calculating expansion factor, it considers a parameter called P2/P1 which it calls as "Pressure Ratio" for orifices. The description is given as the ratio of absolute static pressure at downstream tap to absolute static pressure at upstream tap.
Can someone help me please with how to calculate this pressure ratio for orifice (P2/P1)?
Thanks in advance.
