CFV is calculated by dividing the volumetric flow rate [lpm or gpm] in the flow channel by the cross sectional area [m2 or ft2] of the flow channel.
How to calculate crossflow rate?
Tech Tips: Cross Flow Velocity (CFV)
- Flow channel cross sectional area: Channel depth x Channel width* = 0.23 x 3.92 cm.
- Flow rate: 1 l/min = 1/60000 m3/s.
- CVF = (1/60000 m3/s) / (0.0023 x 0.0392 m)= 0.18 m/s.
What is crossflow rate?
Crossflow Rate (CF) (Retentate Flow Rate): The recirculating volumetric flow rate of the feed solution through the cassette assembly. ... Diafiltration: The fractionation process that washes smaller molecules through a membrane and leaves larger molecules in the retentate (concentrate).
