diameter using the
graph below
Notes
This chart is calculated at 105
SUS and 120°F for ISO VG32
fluid (DTE-24), values will
change with viscosity changes.
Note
To calculate orifice diameter at
other flows and differential pressures
use the following formula:
D=0.203 x √(Q/(√?P)
Note
where D= orifice diameter in
inches; Q= flow in US gallons
per minute; ?P= differential
pressure across orifice in PSI.
