Find a Silicon Orifice
Knowing gas flow desired and inlet pressure
Follow steps below
Step 1
|
Convert application gas flow (in sccm) to N2 equivalent flow Divide by the K factor (see table or extended list)
|
|
Step 2
|
Convert application pressure units to P in psia Add 14.7 to psig value
|
|
|
Step 3
|
|
Find the silicon orifice model number by matching the converted flow to the best value in the column for P
Note, if P isn't a table column convert to 20 Psig by multiplying flow by 34.7/P
