# Apparent porosity calculator

The calculator calculates the apparent porosity for given values.

The porosity constitutes the part of the total porous rock volume which is not occupied by rock grains or fine mud rock, acting as cement between grain particles, means the amount of pores within a volume of sediment or porous solid. The value of porosity is measured as a percentage/fraction. The Porosity includes the volume of the sealed pores.

#### Formula to calculate Apparent Porosity:

Apparent porosity = ( s - w / s - i ) * 100

**where,**

s - weight of piece soaked,

w - weight of dry piece,

i - weight of the piece soaked and immersed.
