Szacowanie współczynnika filtracji w kolumnie filtracyjnej

In this paper the expression on filtration coefficient at variable level of water in column is obtained. Subsequently on found that height of water column is independent random variable and one posed expressions on function of density probability of volume h, function of distribution, expecting value and standard deviation. At the end testing of filtration coefficient of glass sinter in filtration column at variable height of water column is described.
