Analysis
Flow Rate Ratio
The flow rate ratio (Fr) compares flow rates across the filtration to characterize the test behaviour.
Inputs
Fr is derived from the filtration curve. Volume-based flow rates require the filtrate mass density so mass can be converted to volume.
Warning
If volume data is unavailable, fill in the filtrate mass density first.
See Test & Sample Data for where to enter it.
Result
The computed flow rate ratio is reported and included in the Excel export. Use it alongside the specific resistance to assess filtration performance.
