Hi

I could not understand how they calculate flux from permeate weight using the following data.  

The filtration area of membrane is 13.4 cm2


Time, T(min)            Permeate weight (g)      Flux (g/13.4 cm2/min)

1                            23.04                              23.04

2                           46.05                               23.01

3                           68.98                               22.93
....


10                          229.1                              22.87


Hope to help from you.


Sincerely yours

thank you very much. they got data every minute with the same fluid and its simple cumulative system.

For minute 1, flux is (23.04-0)= 23.04
for minute 2 , flux is (46.05-23.04)= 22.01



sincerely yours
