The apparent porosity is illustrated by the image below. To calculate apparent porosity, three essential parameters are needed and these parameters are **Soaked Weight (W), Dried Weight (D)** and **Suspended Weight (S).**

**The formula for calculating apparent porosity:**

AP = 100(^{(W – D)}/_{(W – S)})

Where:

AP = Apparent Porosity

W = Soaked Weight

D = Dried Weight

S = Suspended Weight

Let’s solve an example;

Find the apparent porosity when the soaked weight is 14, the dried weight is 10 and the suspended weight is 12.

This implies that;

W = Soaked Weight = 14

D = Dried Weight = 10

S = Suspended Weight = 12

AP = 100(^{(W – D)}/_{(W – S)})

AP = 100(^{(14 – 10)}/_{(14 – 12)})

So, AP = 100(^{4}/_{2})

AP = 100(2)

AP = 200

Therefore, theÂ **apparent porosityÂ **isÂ **200%.**
