Flow Rate and Pressure Drop Formulas:
Clean DP = Flow Rate x Viscosity x Flow Factor/(Length Factor)
Flow Rate (gpm) = Clean DP x Length Factor/( Viscosity x Flow Factor)
The Standard Length and Flow Factor of Pleated Metal Filter
Length (inch) Length (mm) Flow Factor
10 254 0.00036
20 508 0.0076
30 762 0.00116
Note: Other specifications could be test.
- Clean DP is differential pressure initially, unit PSI.
- Viscosity unit is centistokes (Cst) . If other units, pls convert to Cst.
- Flow Factor is DP/GPM at 1 cks for 10 inch (or 250mm length tube).
- Length Factors convert flow or DP from 10 inch (250mm length) to required cartridge length.
