I have a filter for removal the impurities from the water.. this filter has a cross sectional area about 0.07065m2... and volume is 0.1766m3..
some materials ( beads ) were put inside the filter in order to filter the water.. the packed bed was around 0.60m length..and its volume was 0.046m3 of the filter..
The length of the filter is 2.5m and diameter is 0.30m
the beads ( materilas ) inside the filter need to be washed from time to time.. for this reason we use water or air for backwashing
My question: how could we know how much water or air that we have to pump it to the filter to clean these materials ?
You can make any assumptions if u need
I really need your help to solve this question.
Best regards
