Sie please explain this

can Where, n is porosity, V v is volume of voids and V is the total volume. The porosity of rocks can be determined by drying the sample to a constant weight and reweighing it after saturation with water The volume of water absorbed can be calculated from the following equation: 100x W -W XD n V Where, n is porosity, Ws saturated weight, WD dry weight, V volume and D density. During natural formation of rock pores, voids and interstices develop. Such originally developed porosity

    Porosity is the (pore volume / Total volume of the rock)* 100 in percentage. If we dip that rock in water that the pore space will be occupied by water so now weight that rock let it comes 50g then dry it so that it will be totally water free then weight it again suppose it's 30g. so water went inside the rock is 50-30=20g so water occupied in rock has a volume of the pore exactly so volume will be volume= mass/density of. water( that is pore volume) now this volume /total rock volume * 100 =porosity in percentage. Here the formula is little wrong That "D "will be below the fraction
