In Back pressure type pneumatic gauge, there are two orifices. What is the relationship between upstream pressure of first orifice and pressure between two orifices?
A. Depends upon the distance between two orifice
B. Depends upon relative size of orifice
C. Only on geometric area of first orifice
D. Distance between pressure source and first orifice
