    It has been found out that head loss in the filter is h = 4,5 mH2O. Solution: Let us calculate filtration rate (the correction coefficient as equal to 40): w = 3600·c·d²·h/l·(0,7+0,03·t) = 3600·40·[0,0005]²·4,5/1,6·(0,7+0,03·20) = 0,13 m/sec. then we find passage area of filtrating layer (where F = filter area):
